I just received my monthly T Mobile bill, and was surprised to see an $8 "Payment Support Fee" charge. When I phoned T Mobile, I was informed that I was charged because I had phoned their account department to get assistance changing the credit card that I use for Autopay. I had phoned them because their "add new credit card" function on their website was not working - a problem well documented in this forum. She reversed the charge. But it should never have appeared in the first place.
So T Mobile charges $8 if you phone them for account support. This is both unreasonable, and uncommon.
I only hope that they don't charge me another $8 for my phone call asking them to reverse the first unreasonable charge!
I have been a T Mobile customer for years, since it was called "Voicestream." I've been very happy with them, especially of late, but this type of shenanigans really leaves a bad taste in my mouth.
The only reason to get charged that fee is if you:
Make a payment with a rep or creating a Payment arrangement over the phone
Who ever answered you with
"had phoned their account department to get assistance changing the credit card that I use for Autopay"
was just too lazy to find the real reason. As the name denotes, it's a PAYMENT fee
