No connection. No service. Customer service worse.

Been having connectivity problems for the past 2 months. Was told by the consultant to call in everytime I have a drop in signal, which I did. Each call was a minimum of 15min per call. Been asked to change settings. Unplug electronic devices, all of I did. Yet no one came with a solution. When asked to send someone to come assess my problem I was given long stories. So im basically paying for something that is not working properly.
