"Internal revenue service. We wanted to call us back at the very fourth hearing-about(?) the message as the issue is very seated. There is a lawsuit filed against you by IRS offices. So before the things go worst against you. Call us back on our hotline division which is 703-822-4917. I repeat it's 703-822-4917. Don't disregard this message and do return the call. Remember the delay in calling us back or any other discrepancy with this matter into a legal ... on your needs. So we hope that you justify this matter as soon as possible. Thank you."
