I called them up they said it was a business/company error my money would be back on the card at -. - comes my money is not there, i call again at - on -/-/2015 they then tell me its my fault and i have to wait 8 days to get my money back. I am so fed up with speaking to these people. How can they just take my money and get away with it. I spoke to a guy name - he claim he was corporate, but there was nothing that he could do. I have to wait 8 days. That money was to be used for bus fare for me to get to work until i got paid I have not been able to go to work or eat because of this situation. It 's not fair. They should not be able to just take my money and not put it back on the card. I do n't understand that. They did the same thing with my girlfriends card but put her money back on the card at -. Please help with this situation.
