I answered phone and received silence then a hang up. Called the phone number back and got message that they were for a government tax relief program and sorry they missed me. I then got the option to push #1 speak with someone or #2 be put on their do not call list. I'm already on the Federal Do Not Call List. If they're selling something this isn't a very good way to do it.
Called and didn't leave a message. Caller ID shows up as "Tax Help Center". Did a reverse phone look up on whitepages.com and it's flagged as high level scam/fraud. Another number they call from is 605-679-6932. Looks like another IRS scam.
