Trouble shooting guide on line is a joke! Only addresses one problem, no dial tone. Phone stopped working yesterday afternoon, have dial tone. All attempts to dial out result in the "fast busy" signal, all incoming calls go to Verizon Voicemail immediately. Called "customer service", they checked the line, it is a copper line, (no FIOS in our area or plans to add it) said there is a line problem. First availble service call isn't until 12 Aug.! We have spotty cell coverage at best. Nice job Verizon, Customer Care is obviously not an important issue. And of course, attempting to post this results in server error message , what a joke Verison is!
