I know its a lot of trouble but please write to:
Enough written complaints might help resolve at least some of the issues. The FCC has the power to fine RCN for some of their egregious "errors".
I've had consistent problems with the alleged "high-speed internet" for which I am paying a premium price. The service is consistently slow and frequent "outages". I also have their cable and I am unable to watch Netflix or Amazon streaming services (which I also pay for) because there is "insufficient insufficient bandwidth".
