Who called from 9512405505

Same call & message was the same. I've blocked them every time & they just call back from a different number. Keep on blocking.

202-866-0718 is a SCAMER number claiming to be IRS.  Do not answer this number or call it back. Very poor scam that some people may fall for.

Received very threatening phone call from 951-240-5505 stating they were with the IRS and that I needed to call back or have my attorney call back immediately before everything comes falling down around me and my world. Called back and told them that I knew that they are not the IRS and why they were doing this, and they hung up.

Same exact type poorly recorded message saying that if they did not hear back from me or my retained Atty of record, they could only wish me luck as the situation totally unfolds on me. Eegads!
