Store: Westfield Stratford City - Carphone Warehouse. Utter garbage customer service. I purchased a phone and case 2-3hours before going back for a refund. First guy I approached, I asked whether this certain phone has a dedicated phone case for sale, he said "no". Then he turns and walks away. I turned and tried to call him back, but I ended up making eye contact with another sales assistant. He served me from start to end, I even asked him a similar question, regarding the phone case, he said "we have it", then shows it to me! I decided to purchase the phone and case. (In my mind, I was cursing the other jackass, thinking he knows it all then FKS UP!, also, he heard the guy say it.) Even though he made a few mistakes and took some time with the transaction and asked the assistant manager for help (but he was far too stupid to help!), he then asked another sales for help. KUDOS TO HIM, he was new. Few hours later, I went back to the store. I PERSONALLY HAD TO APPROACH FIVE!!! YES FIVE!! different members of staff (including the assistant manager - TWICE!!) to get some sort of assistant on a purchase! They all gave me literally 10 seconds of their time before walking away! I WASNT EVEN FKING DONE TALKING!! No refund! Only part exchange for another mobile device!
