Rain isn’t what I thought. Terrible connection.

I signed up for a Rain internet package, they were so quick and helpful. 2 months later, and the internet is terrible! I can’t do things on my laptop and watch tv at the same time. Thats how bad it is. The mbps is 0, multiple times a day!! I asked Rain to come out and see what the issue is, but they don’t even bother calling me back.
