Who called from 7203269927

Received a third call from this number stating that they are from the I,R,S, and I had to call this number immediately to stop any action.

Called but left no message. Further research shows it as a Cingular cell service number. I seriously doubt it's the real IRS as stated in previous posting.

2 calls with messages about being the IRS and to call them back or they will sue. Reported on the IRS.gov website.

Got 2 calls and voice mails, stating that IRS is suing me.

Sorry, the number that called both times was the same: 720-326-9927
