I received a message from this telephone number stating that I needed to return the call immediately; that they were "serious allegations against me". So I immediately called the number back and it said the number was out of service. I listened to the pre-recorded message again and it gave a different number to call. I called that number and a man who barely spoke English told me he was from the IRS and they had opened a case against me for tax fraud! I explained that I used a hired service to do my taxes so I know they were done correctly and I asked him to give me more details and he hung up on me. I've heard of the scam going around where the "IRS" calls you, I had never had it happen to me until today.
