What is a "payment support fee"??

It's a charge if you if you went to a store or called support to upgrade you'recharged a fee to upgrade.

Interesting… I did not ask for any upgrades, I just wanted to restore my setting including the auto-pay. And they have charged 10 bucks. Wow...

It's not just for upgrades. They charge for using the customer service support. I've called numerous times in past,  for different things such as help with payment arrangement,  and they charge $10 for all of it. It was over 6 months before I noticed. 

That's crazy. I was charged the 10.00 too. I didn't upgrade either. Guess made mistake of calling customer service. Don't won't happen again.

this infuriates me... I knew it was too good to be true! I switched from xfinity and I DID think that tmobile is 20989% better,. mqybe thays not sayin alot anyways...  

they should have to tell you about the charge. "fyi, this phone call is going to cost you $10 for me helping  you with our Services, even though you already pay for our services & seems like the help should come with it". or when you sign up! 

What company charges you to get an upgrade!!! you're already getting an "upgrade"!!!@!@*&><^=/$"

I didn't even get an upgrade! 

WOOOÒOOOOOW!
