Who called from 6233885985

Spam junk calls, even though I am on the do not call list. They don't do anything about this. Try to call back the number is busy or does not ring.

I just received a call from 623-388-5985, and it was a per-recorded message about lowering my credit card Interest rate and when I pressed #1 to speak to someone the male that came on the line was very NASTY, and when he was asked how he got my # he got even nastier and started saying he is the one who "F's" me every weekend and started to cuss at me and when I advised him that I was contacting the police he stated "Oh, yeah I'm really scared of them P****** " and hung up on me.
