It sounds like your woes are more recent than 60 days anyway. If they are charging you for services and then providing you with inadequate equipment, then they are wronging you now, not just in January. What I would do is to go as high up the totem pole as possible and see about getting this fixed without legal action. It is Comcast and, if you sue, they will have top lawyers on it. This will likely mean it will cost you quite a bit to take legal action. You will also likely run into the problem of the fact that you accepted their credit of the measly $20, which may be seen as satisfaction of the wrong. So, first step is to contact Comcast and keep asking to speak with whoever you're speaking to's manager and see how high up you can go and then, if they don't fix it, drop them.
