really you say its frontier. Well then they should know their customers information and should identify themselves when asked. They have been told repeatedly to stop calling us. They tell us they are with the phone company but they ask for my father, who passed over a year ago and they were notified, the bill doesn't even come in his name. So the fact that they ask for someone other then the customer tells me that they are not actually the phone company. I think its a scam.

Please stop calling the number is unlisted so pleas so stop calling

Have caller ID..... if they wanted me to get ahold of them them could leave a message.  How do I stop this.  I owe no one and have excellent credit rating

Got a call. No message left.

I keep getting a call from 866-252-5910 every half an hour.  They never leave a message and are very persistant.  Anyone know who they are?

We receive a call from 866 252 5910 almost nightly.  If the answering machine picks up the call they never speak or leave a message.   Very annoying but we never answer when this number calls.  Would love to know who is harrassing us.

Called a few minutes ago. I answered - a message started to play then was cut off, and a person was on the line, but sounded like she was talking to someone else. Then the call ended.

This call is from Frontier Communications.  They want to tell you about special additional features for your telephone service.  (And to charge you more for.)
