Who called from 6463571709

claims to be irs warning me they are filing lawsuit against me, then proceeds to ask me my first and last name. told him to send me a letter and he hung up

As of 11:40 today they have called 3 times, each time it had been an automatic message saying: They had been trying to reach us and this is the final notice, the IRS is filing charges against us and we should call this number 646-357-1709 for information.

Same thing... as of 4pm today they have called 4 times stating that the IRS is filing charges against us!

Telling me this is the final notice that the IRS is suing me. That I need to call this number to have it resolved.

They have called me 4x in7 hrs.  They say the IRS is suing me and give this number to call.  Sounds like many people in the room , like telephone sales.
