I went to one of the Metro PCS Corporate stores to pay my phone bill. The lines are usually long and on a previous visit, the customer service rep suggested I use "their" Automated Payment Center located right out front. So the last 2 months I used the machine. You do not have to have exact change. My bill is $52, I put in $60 and receive $8 change and a receipt verifying my transaction. Last night (Dec 1st), I used their "ATM". I put in a $100 bill. It processed my $52 payment and said to collect my $48 change. Their was no change. My receipt does say that no change was returned and to call a number printed on the receipt. It didn't work. So I went inside the Metro PCS Store (a corparate store mind you). The customer service rep said, "We have nothing to do with that machine. It's not ours. It's a separate company. They just process payments for us, you have to contact them." Naturally I was outraged, especially since they suggested I use "their" machine. They threatened to call security since I wouldn't take no for an answer. I finally located another phone number for "QPay". They told me this morning that I have 2 options, apply the $48 to my next payment, or wait 4-6 weeks for a check. More outrage. Q-Pay and Metro PCS are liars and cheats. I want an immediate cash refund. I paid cash, I want cash back NOW!!! I am complaining here, the BBB, Ripoff.com, LA Times, OC Registar, OC district Attorney, State Attorney General's Office and the FTC.
