ACS Inc Email regarding possible lawsuit Internet

I replied to the intiial email communication from ACE Inc b/c, as most, I was concened when I read this 'bizarre letter'.  More importantly, I had no clue what account/debt that these guys were referring to...just their internal reference 'case file #' assigned to my case.  Why would I agree to an "immediate settlement" offer for $560 (original loan amount was alledgedly $300) w/o being able to ID the creditor??  Days overdue??  A refererence or account # I may have seen before???  More importantly, I was uneasy to say the least - that the ACE Inc revealed just enough info in their email to be dangerous - scary, actually.  My bank was namedw/o ref to my acct #, my IP address & my SSN were referenced but no numbers???

Since all I had to go on was the originating email addressee I sent my reply to him asking him to provide further details relevant to the co's or the creditor that they rep'd to any efforts to contact me re this debt.  I received an immediate (it doesn't take long to find/complete the template, go-to response) reply that said the following (in bold below):

This is ACE (Advance Cash Express), it is a mother company which owns and operates more than 350 websites, you applied from one of our website and you never bothered to pay this debt, so the creditor wants to know your intention about this matter of yours that what would you like to do.

And we are talking about the loan amount of $300.00 that you took with the company ACS – Advance Cash Services (A Parental Pay Day Advance Company), using an e-mail address (my email address correctly filled-in this field). They do have a signed copy of the contract which is signed under your e-mail address, also would like to mention your computer's IP address and your SSN was also traced when you were signing the contract with the company.

The company has more than 14 technical evidence in order to prove the money was successfully deposited into your bank account with Bank of America.

As you are looking to settle this matter outside the court house, the best we can do for you is -
 
1.  We can provide you the Settlement Amount of $560.00 that has to be paid at once till April 26^th 2014 or,
 
2.  If you are looking for a payment on the settlement amount, the Settlement Amount would be $700.00 and we can split it into two equal payments each of $350.00 that has to be paid till May 10th 2014 or,
 
 
3.  If you are not able to work with the given settlement amount then the best we can do for you is we can split the Total Outstanding balance which is $986.45 into four equal payments each of $246.61. Kindly confirm us the four dates on which you can make your payment of $246.61 each.

 Kindly update us with the payment date and the amount so that we can suggest you the mode of the payment accordingly.
  
Do reply back soon.
  
 Regards,

So - not much in the way of details esp when I was told I was going to be "legally prosecuted" in the initial email from this co. 

However, it looks like most everyone else was given contact information if they wanted additional help. I did NOT get any contact information as it pertains to ACE Inc.  It looks to me like most of you were given phone numbers, names, etc. 

Did anyone call??? EMail??  I know the answers but different people have different experiences and different states require more/less from debt collectors, esp payday loan collectors. 

What if anything are you doing about this??  It's just a matter of time before someone else tries the same thing using the same info these guys bought from some sketchy company.  It also seems like the ACE Inc operates w/in the Gmail serivce.  That is to say the co that boasts owning/operating 350 websites, law teams, etc should be & would be using their own mail systems - unless Gmail or other servers were spamming them w/o the Gmail address????
