Att overcharged me for two months. I called to asked them about it, and they said they upgraded me to a new service. I told them my speed hasn't changed and I would gladly accept the new price if they increased my speed. They agreed. For two weeks I had half the speed, I called them many times and got disconnected. I couldn't stay on the line for 45 minutes on a work day. When I finally got a hold of them, they apologized and fixed the issue. They promised me a free month of service. That's where things got interesting. Maybe it was a bug, but every month, I got credit instead of a bill. So every month I was getting -20 dollars. A whole year passed. I never complained. If it was a good company I would report it. A year and a half into it, it was fixed. I got a call to ask me if I was paying my bill. I answered "totally"
