Got a call from these people at 7:00 in the morning.  CID said "Cell phone AZ".  I picked up because we have family there and thought it was them.  Wrong--- computerized voice with American accent claiming that this was the IRS calling with a final second notice and we needed to call them back.  I was so pissed I can back and told them they were [***] for calling at 7 in the morning.  I called back two more times and each time got some with a heavy, I mean heavy accent claiming to be from the IRS, so when they answered, I made sure they heard the toilet flush.
