ACS INC. Payday Loan Internet

 I keep these emails from this Payday Loan Company.  I do get payday loans but not from them.  They say in the email they have my social security number.  That if I go to court it will be a total of $3863.56.  But if I want to resolve it the court costs of $980.88. I would have to pay that now.   I never taken a loan from them.  They tried calling a few months ago several times a day.  It was so bad I had to change my phone number.  On the phone they threatened I will go to jail.  And this is check fraud.  I would like this to stop the people calling need to look for a legitimate job.  Plus, I am about to retire I do not need any aggravation from these people.
