"I went to a restaurant on T-Mobile Tuesday, excited to redeem my free pizza, only needing to pay the taxes, which came to about $4. I ordered the pizza online and was given a pickup time. However, when I arrived, the manager informed me that I couldn't pay in-store. I attempted to pay online, but there was no option to enter the CVV code, which is necessary for card verification. The manager also attempted to process the payment and saw the same issue, yet he refused to accept cash. The website indicated that I could pay either in-store or online, so I was quite frustrated with him for denying me the pizza. I've been a loyal customer of T-Mobile for years and have never encountered this problem before. The manager suggested I call T-Mobile instead. I believe he needs more training; accepting my $4 could have kept me as a happy customer, but instead, he lost my business."
