ACS Incorp Cash Advance USA Final Legal Notice Corvallis Oregon

I received two emails dated on March, 23rd. One from Cash Advance USA and the other from ACS Incorp both stated that i owed them money for a loan that i got. Ive got two case numbers and two different amounts owed. They are CASE NO# 45D/1271A for $935.45, and CASE NO# AVD-00151/S for $986.67 with a reference #47895658. That if i didnt respond back within 24 hours of the email to set up payment arrangements they was going to take legal action against me. Apparently, I received these loans back in December, 2014. If is was to go to court the amount that I would have to pay would be $6300. I really feel that something should be done about what these people are doing and how they are trying to ruin peoples lives. I mean really when I recieved these emails I was shocked and and quite pissed off because i really truely believed that maybe someone in my family used my name or my identity was stolen, but then I called up Cash Advance and they notified me that they dont send out emails in trying to collect an debt and was told it was a scam against me. I want something done about this or im going to action in my own han, this is REDICULIOUS!
