Unless a person has totally been living in a cave, with NO outside contacts - radio, TV, newspapers, etc. et al, they (should) know long ago that IRS does NOT call ANYBODY, but instead does EVERYTHING ( that's EVERYTHING) in writing. If you get any other form of communication, purporting to originate from them, you should know IMMEDIATELY that it is a scam - no ifs, ands, or buts !! Do NOT ACCEPT any other form of communication, allegedly from them.
Another day, another scam, tax relief, tax consolidation, Irs scam, credit card scam, it never ends. So, before i block, i picked up and told the lady that the recording said they were going to pay my debt off, she said you need to listed, we will consolidate your debt, i said NO, you said you were paying it, so give me your credit card number. She hung up.
