The honor order from Costco I bought The Pinguino Plus Arctic Whisper Portable Air Conditioner with Heat and ECO Real Feel. Item # was 1491242 it was the black unit for 700 square feet cooling. The next day Costco changed the same item number to the white unit,  Which is the lower class cools 500 square feet. Item number was 1491242 when I bought it. Next day same item number 1491242 but with different AC unit  the white one Same company but lower class. I also took screen shots just in case.  I knew something was fishy about it. I called Costco to find out what happened? I  They told me now it's in white color and they don't know what happened.  I said I want the black one that I purchased, not the white one, they  told me if I receive the white one call them back for exchange. UPS came and delivered the white unit. I called Costco again,  I explain what happened, The lady said  that they don't have black one in stock, she told me when they will get the black one they will ship me the black unit and take the white unit back. In couple days I checked Costco website on 3/25/21 and it's back, the black unit, with item number 1491247. So I called them back, they told me no no it's not in  Stock. I told them I am looking at it right now..  I also told them now it's under different item number only then they could find it..  I also told them that the girl told me that when they will have the black unit back, they will do the exchange, They told me that they will leave a note for the exchange in the system. But now it's under different item number the same unit with price $599 But when I bought it it was $499. I called them back and asked to do the exchange for the black unit... Then they refused to do that. They told me it's under different item number and that they  can't do it..  I told them it should be in the note that coustemer service left for the exchange..  They told me they don't see any note. i told them again I purchased the black unit so I want the black unit, and then they told me that I purchased white unit. Really??? I told them no I did purchase the black unit. They told me on the system it showed that I purchased the white unit.. So I looked at Costco email that they sent me  for this purchase, and yes it was the black unit, not the white one..  I told the manager that I want to send her screenshot of email back to her so she can see that it was the black unit, not the white one.  She sent me email and I did reply the screen shot. The manager told me that she will call me back in 15 minutes, her name is Karen. About 3 hours later no calling back to me. I called her back to her personal phone number the one she gave me, but she didn't answer the phone. Afcours why answer the phone when she clearly can see that it is the black unit.  Called her back later during the day, and no answer again. Looks like she's ignoring me now. Called Costco back and asked what's the status with my purchase, I spoke with Dia, he told me that's impossible to send me the black unit, because he said I purchased the white unit. And I'm trying to change the product. I told him That I have proof email from Costco with the black unit, and I also took screen shot of the black unit and the Item number. He said no, it's the white unit and Costco doesn't change units with the same item number. I  Told him I have screenshots I have proof, even email confirmation from Costco with the black unit. Afcours it's in white color after Costco changed it from black to white the next day. And the difference now is $100. Even after I provided them 100% proof, they still not willing to send what I purchased. Now I have to waist my time, fuel, driving to Costco and return it. I spend so much time on the phone with Costco fighting to receive the unit that I purchased.  Also lost my appetite for that day.  Then I spoke with other lady from coustemer service,  she told me that lower end unit that cools for 500 square feet come in black color and white color, so they didn't had the black one, and  That is why they sent me white one. Then I called the manufacturer link: https://www.delonghi.com/en-us/products/comfort/air-conditioning/portable-air-conditioners/pinguino-pac-el290hlwkc-1a-bk-0151862208 There phone number: 18003223848 I asked them if they have  This unit in black colour that cools 500 ft².. They told no, they told me the black one is higher model for 700 sqare ft, and  the white one is lower model for 500 square feet. That means Costco doesn't have the lower model with 2 different colors. So now I probably know what happened, Under this item number 1491242 They sell the white unit. But who ever uploads information and pictures they uploaded Black unit Under wrong Item. The black unit cools for 700 sq feet, that is why the next day it was charged to the white one. I don't see any other explanation of this mess. Costco I did purchased the Black unit, so please send me what I purchased. Costco If you made mistake it was on your end.  Not my end. And stop telling me that I'm trying to change the product. Stop blaming me for that mess. Next day I called Costco manager Karen and asked her what's up with my  purchase, I also had to explaine to her what happened, that Costco uploaded the black unit under white unit Item number. That is why next day it was charged to white one. Then she told me that I purchased the white unit. I told her it was black unit, plus I did send her screenshot of email that they sent me, and screenshot from Costco website with the black unit. She still did not agree with me, after all 100% proof was sent to her. She told the only option I have is to return this item for refund, and repurchase the black unit.  If I do that I will pay more mony for it. And yes it's $100 more  on Costco website. She also spoke with me with  NOT friendly tone, like I was her  worst enemy.  She needs to be more friendly to costumers. I could feel her extreme anger when she was taking to me..  It was the WORST purchase from Costco I ever had.  And the worst costumer experience I ever had with Costco.
