Greatcall has not been working for over a week now and with a 92 year old husband with stage four cancer I can't even make a call out to his doctors about the symptoms he is experiencing that were not expected. Greatcall never notified us of any type of update to the system or any other matter, this is beyond forgivable! As soon as I can I will get a different provider and never go back. This is ridiculous. Greatcall, get your act together!
