Home life app and web cam

I have a minimal installation of Homelife -- a door sensor and a camera. I signed up for a bundle. However, the camera has not worked. I constantly get a "communication failure" message on my iPhone app. I have had a tech out twice and they don't know what the issue is. We swapped out the camera, but that did nothing. This is pretty frustrating and I would like to figure it out. 

I tried to cancel the service, but that would make my bill go up.
