Who called from 6575495913

Got several calls. One be said she was heather grey from the irs. Sounded like a very bad automated attempt. Called them back and said I had missed a call from the # +1 657-549-5778. I asked where I had called and he said I must have a wrong #. Funny how do u have a wrong # if they called u first?

They called at least 10 times today. I told them I know it's a scam please quote calling. He said he'll call me as many times as he wants
