I had good internet for past few years when it was called ATalk so a 4 star for that but 2 years after telehop came on internet frequently stops working and phone support lines have been out of service for past hours...
we had alot of issues with our internet so we finally cancelled after many many hours of customer service
At this time Telehop has blocked my number and I can not call them. I use someone else's phone to call them as we still have a terrible long distance plan with them. They deny this but when ever I call them from my cell the call gets disconnected.
