Here is what you do:
There's a address on the bill for mailing them. You write a DNC letter and send it via return receipt or certified mail. Even you phone company can not call if you tell them DNC. They have to place you on their internal DNC list. You can tell them on the phone also when they call! They can get into trouble if they do not, but I found its best to follow that up with it in writing.

Frontier sales pitch.
I pay them $9.99 per month for caller ID, then they have the nerve to make sales calls to me where the number shows up. I think I will drop caller ID. Maybe i should just drop my hard line and go to a cell phone

This is Frontier's number ... They handle my internet and cable services and CONSTANTLY call to try to upsell me.

A call came from this # and who ever it was is not to Smart, some lady left some rambling message on answering machine that made no sense at all. Learn english before making calls.

Anyone know who this number belongs to.  Will not leave a message.
I am on the do not call list.  Am tired of it.
