I have received numerous calls from this number and didn't answer until this morning. It is someone of Indian descent, I believe, and I could hardly understand what they were saying. I told them I didn't know who they are.
I got a call from the number 424-253-0694 a Richard Rollins saying he was from the IRS I explained that the IRS does not call you and say you own them money and they also give their employee number. I told him that I work for a telecom company and the call was being recorded and all of the sudden he said he would remove my number and would not call anymore.
