acs corp none harrassing calls and emails florida

acs corp harrassed me by phone sayng i owed them 862.41 and if i didnt pay them they would sue me in federal court for $ 6600. i never dealt with them they even had my wifes social security # wrong and her birthdate. they tried to get right info from her she wa smart enough to not give them anything. i filed complaint with illinois lisa madigan attorney general and with ftc ,and numerous other companys i could think of ..this is a complete scam they wouldnt give address or papers of loan  when asked ,they need to be arrested and put out of buisness. it was an non english speaking person with overseas accent like a indian or something,very rude  forceful said he would stop my income tax ,report to my credit bureau,  thia is a sham now there phone number is turned off after i filed numerous complaints,  beware and call government agencys to file complaint.  $6600 dollars over a 800 dollar debt we never did , crazyyyyyyy
