net spend stole my money Nationwide

I have been with net spend for alot of years.I only use the card sometimes,2 weeks ago i went to put money on the card and it says the card was closed and to call customer service.I did and they said i owed them 80 dollars( i dont know how when its a pre paid card) and if i would like to open another account i can (they said a person can have up to 3) and when i asked about the 80 dollars thery had said its up to me if and when i would pay it(should have known better) and if i open another account it wont be affected.I actually called 3 seperate times to make sure!!  So like a dummy i went and put a 100 on the account yesterday and of course they instantly take my 80 dollars!!!!!!!!!!!R u kidding me??I wait 45 mins on hold( at work) and am told that the 3 people were wrong and they could do that cause they claim i owed it to them.So basically they just stole my money!!
