I was really looking forward to getting a new mattress through Amazon as a Prime member. However, my order was canceled for no reason, and I had to talk to one of their customer service agents. The agent apologized for the mix-up and told me to place a new order for the same mattress. But here's where it gets fishy: the price of the mattress had gone up by 65 quid. The agent said not to worry, and that I'd get a refund for the price difference, and I believed them. They even messaged me saying, "I’ve requested an amount of GBP 64.01 to the original payment method. It should be deposited by your bank/card provider within the next 5-7 business days with no issues." Unfortunately, I never received the promised refund, even after calling Amazon a week later. I can't believe that an Amazon customer service associate would lie to me like that. As a Prime member, I expect better service from Amazon. Just be careful when dealing with their customer service.
