Received a call from this number (on my cell phone) with a recording saying something about case file and to call back at the number that called. They called back again an hour later and left the same half of a message. I do not give my cell phone number out to anyone I do not know so if I receive a call on it and it does not come from one of my friends I do not answer it. I have a plan with very limited minutes for emergencies only.
Claimed to be from IRS. Obviously not speaking American English as a first language. Had a very hard time with my name. I immediately became suspicious that this was not a legitimate call, and said the same before hanging up.
