Another random number. Called. Left no message.

484-220-1180 calls me every month & no one is there...dead air when I answer.  If I dial the number back, there is the recording that says press 1 to be on the do not call list but then dead air & nothing ever happens- they keep calling.
The number belongs to Paetec and they distributed it to Telecall Management.   You can call Paetec @ 877-340-2600 & complain and also call Telecall @ 307-223-0458 and complain & ask to be put on the dnc list.
