A very long time ago I had internet (but not cable tv service) with Comcast. It was generally mediocre reliability, but it's the only option we had. At some point, the service just up and went out entirely.

For approximately two months, we had absolutely zero internet service, while Comcast continued to collect our monthly fees. We kept calling, and they kept sending out tech after tech. I don't recall what the final tech fixed, but they complained that all of the previous techs should have spotted the issue. We never got reimbursed for those two months of non-service, but we did magically start getting cable tv after the final tech visit. We figured it was their gesture of kindness for the Comcast hell we'd been through.
