I love the way customer service upgrades the acct benefit for the month if customer has a complaint. They are really trying to make customers happy which is excellent service. However, I returned a phone back to tmobile irmo location and mngr issued me refund paper and said corporate off will mail me check. That was 3 months ago. I'm going round in circles with customer service and the store Mngr for 3 months to get my $180 refund. T-Mobile needs to have a better way to get refunds issued to customers 4 valid returns. 3 months is way too long. When store Mngr said T-Mobile would send me email to resolve the refund issue, T-Mobile just sent me email to go back to the store manager. I went to the store Mngr 4-5 times regarding my refund. I hope to get my refund soon! I spend lots of money, time and gas money to keep going back to the store Mngr regarding my refund. I call customer service and they always refer me back to the store Mngr. One time, the store worker told me there's nothing they can do to help me since the corporate office is the one that issues refund checks. I got the impression that the store isn't allowed to issue me a cash refund because their store doesn't hold that much money?
