This is my 2nd contract with Carphone Warehouse and I've never had an issue until this last 2 weeks. I took out a contract for the Samsung S7 Edge which is one of the more expensive phones and came out with a good deal and was pleased with the service I received. Recently a red line appeared on my screen which turned out to be dead pixels so I went in store to get this resolved. It took 1 hour to just simply send off my phone to repair! I was dealing with a trainee so I understand he was learning but he couldn't get my sim card out and when he did, he got it stuck in another phone! Then if it wasn't for his manager noticing, I would of left the store with a standby phone which wouldn't of even worked on my network. The phone I was also given to use while mine gets repaired, is the worst phone I have ever used! I have 2 apps and 4 photos. The memory is full! I was told to expect my phone back in 7 days but it could take longer and I could track the progress online. 1 week went by and the online tracker hasn't even acknowledged my phone was received. This concerned me as I wasn't confident the trainee had done it correctly. I googled 'Carphone Warehouse' and used the number I found to ring the store to find out what was going on. They assured me my phone had been sent but the online tracker isn't updated regularly. I was happy to hear they had sent my phone although a bit frustrated because things weren't moving quickly. I used this number a few more times to get updates. I then noticed my bill for the month was £50.95 instead of the usual £38.00. The number to contact Carphone Warehouse had been charging me! I then checked my usage to find more additional charges of £30.51 was going to be added to my following bill!!!!! Again all because of my phone calls to Carphone Warehouse. I went in store thinking I would be compensated in some way for these ridiculous charges but I was offered discount on a phone case!!!! Why on earth would I purchase a phone case??? I definitely could not afford one now due to all of these crazy charges. I left the store angry and called Customer Complaints to be told that it is my own fault and there is a freephone number on the website! Well that's great but if you google Carphone Warehouse you do not get the number they are talking about. If anyone ever needs a number then what do they do? Google it!!!!! I will never ever be using Carphone Warehouse ever again as soon as my contract is over.
