I'm not great at reading over my Comcast bill. Found I've been charged for a service (streampix, like netflix) I didn't even know I had. Charges are about $6 a month, mysteriously added in January. The customer service rep says I have 60 days to complain about overcharges, according to federal law. Is this true? I never ordered this service. Also, even though I pay $10 a extra per month for top internet speed, it's been slow in recent months. Just got a notice from Comcast saying my modem, which they provide, is not adequate for top bandwidth speed. But I've been paying the extra since they upgraded in March. I asked them to credit the months I paid for top speed as well as the months I paid for the Streampix. They credited $20, saying that's more than they had to. What are my options?
