Advance Cash Services ACS International Threatening lawsuit Internet

I got several threatening emails from this company called ACS International or Advance Cash Services.  When I tried to resolve originally, they wanted an immediate payment from an untraceable prepaid cash card, as as Green Dot.

I believe these people are bogus, as they threaten to file in a US District Court and try to use a US District Attorney as a sign-off.  I used to work for lawyers, so I know if a US disdtrict attorney is trying to get a hold you, they probably would not use email to get your attention.

They do not inlcude the original creditor name in the email so you have no idea who the original creditor is.

I did not send this people money and I will not knowing that is an attempt to rip people off.
