ACS incorp emailed me over paying back a pay day loan i NEVER took out el paso , Texas

Hi i have received an email from these people saying i  owe them  945.67 for a pay day loan I NEVER took out and if I did not contact them I would be going to court which would be over 5000 dollars and I would loose steaming from Sept 25th 2010.  at the time I was in TX trying ot get home i never took out  a pay day loan. i wound up calling family for money to get back to Wisconsin. which I did i even called my  bank they said only thing which was deposited in that time was my ssi and the money i got from the money gram from my family member which I deposited myself .  needless to say i called this company and well chewed em a new a**.  they were very hard to understand got very rude and hung up which made me madder so i called back immediately an got some one very apologetic and i explained to them and they said well we will l0ook into this im like I do not wan tto hear about this again unless I am not responsible or you made a mistake. 

 the phone number in this email is  1-347-983-0385 and then it proceeded to say if  i can use my debit card and clear this up i was thinking hell no .right now my bank is on high alert with all this going on and they got a investigator standing by waiting for them to try something. I am very angry at this and i would like to see something done please.
