Don't know who this is and they are costing money on my cell service.  I can't see the phone # of the incoming text message, and should I open it, I get charged by my service.

Rec a call stating they were the IRS collecting a debt and to not ignore the call for further penalty.

I received a recorded message from this company saying that they were the IRS and that I, or my appointed legal spokesperson needed to contact them immediately.  It was a scam!
