Never heard anything like this one.
Today (08/31/2015), between 8:45 and 9:00 a.m., I received three phone calls from this number. The caller did not let the phone ring long enough to activate my voice mail.
Looked up the number in an online database and it seems this is a scam for a security system installation.
Claiming to be IRS and must call back ASAP or charges will be brought against me. Didnot specify who is being sought.
It has called repeatedly for the last several weeks.
Included in the message the caller speaks of a home mortgage and that I need to act fast stating that they are the IRS.
If you do answer it no one is there.
I did not answer and they did not leave a message.
I've received several calls from these people, with various actors playing a clerk who wants to know where to send my device, which has already been paid for.
I work over night so these calls wake me up get one at least once or twice a month!
I received 2 calls from this number.
I have told them many times not to call.
