Horrible experience at best buy San Diego Mira Mesa Store! On January 22, I purchased an open box (Samsung 75” TV = $2385 + Tax) and part of the deal was to get an extra 20% off the TV price if I purchase a total teach membership for $200 and there was an additional offer to get $500 + $100 egifts card along with that Tv purchase. I completed my purchase on that day and scheduled delivery to be on Feb 2 2022. 2 days later, I was checking the best buy app on my phone for other items and accidently I found out that the same TV has gone on sale "brand new TV, not open box" and the price was way cheaper than the open box item I purchased but not delivered yet. So, I went back to the store before the delivery day and spoke to best buy advisor (Lydell Betty) who was available to help at that time if I can replace my order with a brand-new TV since the TV hasn't been delivered and it would be cheaper than the open box TV. Best buy advisor (Lydell Betty) offered me an additional 20% off and to keep my order as it is without returning or canceling it. He claimed that he can’t apply the extra 20% before the delivery day and promised to owner me that extra 20% after the delivery day (Feb2). He made/wrote a note on his best buy business card and attached to my receipt and signed it for that 20% which states “approved 20% off the $1900 the price of the TV” and he signed it (I’m attaching a copy of that note). I asked him if I could get a store credit for that 20% for a moment and he agreed but thought about it for a second and changed my mind and I told him that I would prefer to get the 20% back to my Best Buy credit card so I will have less debit. Yesterday, Feb 5, I came back to the store to ask for the 20% that I was promised to be giving after the item was delivered. The same bust buy advisor (Lydell Betty) who convinced me to keep the open box and offered me an additional 20% discount met me again and went to a complete denial of his original offer. He refused to owner me an additional 20% discount. He told me if you are not happy you can return the TV. I was shocked and couldn’t believe what was happening at the best buy store. I told him that you’re changing your word, and this is not what we agreed on and that he noted and signed on his business card regarding our agreement. He started arguing with me then he said he would owner me ~ $ 170 back which is 10% not 20%. After I reminded him about our agreement “Lydell Betty” got upset by raising his voice and sounded condescending toward me. Then he said I promised you nothing and you should have got the store credit of that additional 20% at that time. I asked him if he could call his supervisor over so I can escalate my concerns. Then he said I'm the manager here, Then I said I need someone else to speak to but not “Lydell Betty”. Another advisor “Daniel Delgado” heard us and came to us. I explained to “Daniel Delgado” what happened and showed him the receipt showing his colleague's signature and approval for the additional 20%. He “Daniel Delgado” started working on the point of sale and laughing with “Lydell Betty”. He asked if I still have my original egift cards with me and I said I have a $500 gift card (the one I got with the purchase). He “Daniel Delgado” took the gift card from me and said if you want the additional 20% off then he will cancel the $500 gift card otherwise return the TV. “Daniel Delgado” was even more aggressive towards me and asked me to stop talking and I only have 2 options either getting my $500 gift card canceled with the additional 20% off or to return the Tv. I decided to leave the store after being so overwhelmed. I felt very unwelcomed, and I was lied to by best buy advisors - Very unprofessional advisor! It was the worst purchase experience of my life. I called the best buy customer service line and they advised me to reach out to the general manager of Mira Mesa store and explain the story. Today, Feb 6, I went back today to the store to ask for general manager contact information. I walked into the store, and I asked a very pleasant person who was standing inside if I could get the contact information for the GM of the store. luckily that person was the sales manager “Sal Gomez”. He asked me what’s the matter and I explained to him the entire story. “Sal Gomez” listened without interrupting or intimidating me like the other two advisors did the day before. He acknowledged my concerns and apologized for the incident. He issued a 20% additional discount to me and made me a happy customer. “Sal Gomez” is a very professional and amazing person with high ethics. I decided not to ever buy from the best buy store in Mira Mesa but the way” Sal Gomez” handled the situation made me change my mind but I’ll make sure to shop there only if he’s in the store. It was never about the 20% off as much as the horrible experience that I had with these two advisors (Lydell Betty) and “Daniel Delgado”.
