Who called from 4123390491

I am getting frequent afternoon calls from this number ?  Anyone know who it is ???

It's a sales company and they call all [***] day long. Submit their info to the FCC.

Called twice and did not say a word.  3rd time all he said was my last name a number of times.

Got the same call. 2 hang ups. The third time I answered and started pushing numbers to try to screw up their call system or simply annoy the caller. I recommend it.

I keep getting calls from this number.  I pick up and the person hangs up.
Finally answered today and was a man saying.that he is calling from Vanguard regarding my property (lowering my monthly payment).  I told the man I have been receiving multiple phone calls from this number and that I want my number to be removed...he hung up on me in mid sentence.  When I called back I got an automated message that all representatives are busy.
