Robo Call from a company that keeps changing their number every time you block it. Give a call back number that is an 866 number. I've spoken to them and requested that they mail me the information regarding the debt that I'm supposed to owe them. They never send anything and then stated calling again on a different number. So far I have blocked 4 numbers for these jokers.
The debt was written off in a 2000 bankruptcy and is way past the limitations for collection.
Others have reported that the company name is TACS.
