Who called from 9515527700

Same person called me a Heather Gray

Keep getting calls  from this number say IRS  to call Heather Gray  I block the number and they call from another reporting to IRS

Keep calling - very annoying and rude  scammers.

Callers claim to be IRS telling me I owed money. A local police will be at my house. 45 minutes after hanging up to detained me . That I could prevent this if I had $500 to pay then and they would settle outside court and the rest of my debt can be made in installments

IRS scam-ignore it and do not call them back.
