Poor customer service

I dont know happened, but after using this app for about 18 months it suddenly wont make calls through my cellular network. I contacted customer service and when the finally got back with me they asked me some general questions and then more general question after waiting days....weeks for them to answer back. I asked to send a video and the just said its escalated....again. They were supposed to call and I waited during the 2 hour time and they never did. Very aggravating!
