Don't dial star 60 to block a call if you have Verizon. They charge 50 cents A DAY for a blocked call. Found out the hard way. It will cost you a fortune.
This is the website of the company that these calls originate from.
It is a telemarket company that works for many clients.
Put your number on the do not call list at this link.
I did and so far, so good!
Callers from this number hang up on me when I answer. Why bother to call in the first place?! One of the few places you can actually call back and speak to someone to have your number removed from their list -- altho be warned: the guy I spoke to was particularly slow -- about 1 DNA strand away from vegetable.
