Who called from 2533365321

I don't answer unknown numbers but this one left a message.  Called in from "Out of Area" with Houston, TX number 346-824-5969 then the mechanical voice, in bad grammar, stated they were the IRS and this was their last attempt to contact me about taxes owed.  The automated voice stated the IRS was going to file suit unless I called them back at 253-336-5321  immediately.  Know this was a scam as I pay my taxes diligently, besides knowing the IRS does not call but sends letters.

This phone call person left message they were irs bringing lawsuit against me stop them now

Utterly illegal call!  Message pretended to be from the IRS and about a lawsuit about to be filed - no way in hell does any lawsuit get communicated this way and no way in hell does the IRS do this.  Idiots and scammers, I'll be reporting this to the FTC and the IRS and I hope they never see sunlight again.

Why is SCAM not an option for call type?

Automated message on answering machine saying that this is the Kat notification that the IRS are filing  lawfirms against us. It is false and the message is false. I want them removed.

Not possible, they are located in either India or Pakistan and as such beyond the reach of US law.
