*SIGH*
This is precisely why you actually do need lawyers is to figure out "weasel words". And I did disclose I'm not a lawyer (nor would I ever want or pretend to be!)
"We shall not be liable for any inconvenience , loss, liability, or damage resulting from any interruption of the Service..." That's what starts off the sentence. Then it continues to point out their sole remedy offered as service credit in a completely different sentence.
Basically, if you applied all the conditions enumerated there would never be a credit for anything. Ever. Fortunately at least for some folks, there are state/county statues that cover it. NJ's being "Comcast will issue credit for Video Service outages or service interruptions in accordance with N.J.A.C. 14:18-3.5. " It would in NJ, I'd think, be covered under 'service interruptions'.
The real kicker in the T&C is "Any credits provided by Comcast are at our sole discretion and in no event shall constitute or be construed as a course of conduct by Comcast."
We can leave it to attorneys to debate the word "The". I'm not gonna go there. My original position still remains -- even if Comcast isn't technically bound legally to offer a credit they should 'do the right thing'. True in markets where Comcast holds a monopoly they can hold such a caustic attitude toward their customers. But never underestimate the value of customer loyalty and goodwill.
Trust me I've had my fair share of dealings over 4 months last Oct-Jan with Comcast getting a chronic problem resolved where I was told by CC's ExecSupport to "go to the power company for a credit on your cable modem" since there was alleged interference by JCPL's equipment that took out the entire west side of town. (that's in a different thread: »
[Rant] [LONG]Another Tale of Multiple Truck Rolls ) Eventually I got credits from CC; not the full amount since it wasn't 100% down 100% of the time. But it wasn't a total "tough luck, no credit, go away" either. Common sense ultimately prevailed. Then again, there are times where you just need to remain polite, professional, factual, and absolutely persistent.
