These idiots were calling me 3-4 times a day. Using my FIOS, I called forwarded these calls to another telemarketer number so now all they get is a message saying "this number is non-allocated". If you have this calling feature, use it, it works!
They called again at 10:37 am today, as I was on the phone with my phone company regarding call blocking. Oh the irony! I have the *60 feature, but it doesn't work unless I call the phone company and have them create some sort of trouble ticket for their central office to enter in the numbers. Plus I can block only up to 12 numbers. I've got 8 in there now, including this one. Since apparently none of the numbers are in my "area" meaning with my phone carrier, they can't guarantee that the blocking will work. Fingers crossed!
