Escalating damaged street cable replacement

Comcast customers on [Edited: "Personal Information"] (9 homes) have had tv pixelation issues for at least a year.  Comcast has repeatedly sent techs to attempt various repairs but nothing has permanently resolved the intermittent pixelation.  It has progressed to the point that our tv is mostly unwatchable much of the time.  A few weeks ago a tech who came for another scheduled repair call told us that they had found a stretch of the cable at the end of the street that was bad and it would have to be dug up and replaced.  He could not give me a time frame for when the repair might be done.  In the meantime no watchable tv picture!  It was so pixelated today that it was pointless to have it on.  Even the streaming service was experiencing some pixelation.  And now internet connection drops intermittently.  I'm paying $215 a month for my TV service and I will be demanding a full refund for the months we have not had full service. I believe my neighbors will do the same.  [Edited: "Personal Information"].

Please do the repair now that you know what and where the problem is. I will continue to call for and schedule repair appointments until you do.
