ACS Legal Group Matt Williams ACS Legal Group Ripped me off $200 dollars. Internet

I received a threatening email at work on tues july 17,2012. In the email it was stated that i was deliquent on an account with Advance Cash Expert. I do not have an account with advance cash expert and it threatened legal action which may result in a judgement and that i will be responsible for all court costs and that it will not go to small claims court but possibly municipal court. I was given two days to pay the total amount due of $670.00. It was signed Matt Williams, Collections Manager.  Needless to say, i was scared. i emailed him back and asked what company this was under and that i didn't have a loan with advance cash expert and he emailed me back saying they have 14 technical evidence to prove that i got the money deposited in my account. he went on to write that the company has a signed contract under my email address , the IP address for the computer i used and my SSN. i emailed this person back saying i don't get paid until 7/20/12 . he wrote back and said that if i paid $370.00, a settlement offer, that the loan is paid in full.  I have financial difficulities and have several on line loans so this sounded legit to me and i was scared to go to court so i agreed to the settlement but told him that if i gave them the full 370 that i wouldn't have enough money for groceries, so he wrote back and told me to pay $200 on 7/20/12 and $170 on 7/27/12 that i would be paid in full.  The instructions were to get a MoneyPak voucher for $200 and send it ASAP with my name, address, phone number and the money pak number, which i did through email. Once i sent the information, the emails stopped, i tried calling the phone number listed on the email and all it is doing is giving me a very quick busy signal. No voice mail or anything. i emailed him again asking if the company is a legitimate company and when i googled the acs legal group name and read some of the statements written, the information is exactly the same as what was said and written.  I feel so foolish that i got scammed out of money that i really needed.  I feel very upset and am fearful to tell my husband because he will be angry because when he got the moneypak card at walgreens, the cashier told him that there are alot of people operating scams and getting money from people using the money pak cards and to be careful.  i did not heed the warning and sent the information to this Matt Williams and now I am out of $200 dollars. I will not send the $170 dollars he is asking for on 7/27/12.
