united cash loans and 500 fast cash Took loan for 500 repayed 150 every other week after 2 month's owed 650 still http;//fast cash.com, Internet

I got a card in the mail stating you are approved need money fast call.  When I needed it bad enough I finally did.  Those cards still come in mail today. I got approved for 500.00 then I thought 150 was the finance fee. My minimum payment per two week period was 150.00, I thought till loan was payed off. But I payed 150.00 4 times 50.0 balance remaining another card came in I was still struggling got on internet punched in the code got approved again si I figured I would pay off 50.00 with the new loan and just keep making my 150.00 payments.So got the loan with united to pay off fast cash and keep making it when I found out Fast cash still had 650 balance as if I had not paid anything.When I further inqured I was told every 2 weeks I was charged 150 for the loan so therefore I paid 150 they charged 150.0 more bringing balance back up.I looked at a copy of aggreement it did not look like what I had signed.I asked them to call at my home instead of my job but yet and still they call job 3-4 times daily.My cell another 3-4 times. I've asked them to mail me a copy of my agreement repeatdly right up until today when once again I was told not possible its in the final collection stage.I would gladly pay the 650.00 I understood I owed united cash loans at 150.00 per week and they cant have my bank account info cause I had to close account to stop the first never ending loan.
