ACS Incorp They said I borrowed money from them and that I never paid back ! Online Internet

 They told me that I owed money to a lender. After I paid the amount to settle they said I was all set. Months later I got a email from another lender stating I owed them money for a payday cash loan. I had explained to them that I paid the loan already and sent the the email confirming the loan. They told me ACS Is a scam! I was upset crying after I paid this company. Then to have another company payday lenders tell me I got scammed. I do not have the money to pay the real company because I lost my job. Now I need the scammers to give me my money back because this is seriously ridiculous!
