More Cablevision, Verizon and me

When we last left our protagonist (i.e. me), I was arguing against switching from Verizon to Cablevision. As you might recall, among other problems, my wireless connection stopped working the second we signed up with Cablevision, and Cablevision, after pretty much stalking me to get my business, now doesn't give a rat's ass about the fact that I had to pay $70 for a new router to get everything working again (and it still isn't as good as it used to be). So, twice in the past week, I've called them up and made the point that I should get a $70 credit on my bill and the people on the other end dutifully say they'll pass it up the food chain. I'm happy to provide the receipt. Needless to say, I haven't heard back. Here I am, giving them my business, and they are turning their back on me like this? For now, I'm refusing to pay my cable bill and emailing them the links to all of the posts I've done on this. I feel betrayed. UPDATE: So, just got a call from them. They are only willing to reimburse me for one month's online service, which still leaves me $40 in the hole (not counting, of course, all of the time I've spent on resolving my issues). Their point-of-view: they don't handle routers. My point-of-view: I acted in good faith by giving them my business, and deserve that they act in good faith and give me a $70 discount on my bill. When I asked the person I just talked to whether I could talk to a supervisor, she responded, "I am a supervisor." "Do you report to someone?" I said. "I want to talk to that person." Awaiting their reply.
