I have no dial tone on my phone, it is giving incoming callers a normal busy signal. The bases in my home all say "no line". I have used your trouble shooting guide and suggestions and have ensured that all is plugged in where it should be....but still no luck. I left a message for callback yesterday and have heard nothing. I have also attempted to use your "chat" option to speak to a customer service rep, but have not had anyone show up on the other end. I have a small child and would really like phone service for the babysitter while we are out on new years eve. Can you help??
