"Generous" account credit. What a Joke

We have had ongoing issues with intermittent service.  We changed out all of our equipment at a store a couple of months ago because the guy at the store said that might help.  And yet, almost very evening we have periods of 2 -20 minutes where our service drops.  Most times it resumes fairly quickly.  We often get "something went wrong - check your connections" messages and have gone through various "restart your modem" processes.  Last weekend (Sunday) I finally managed to escape the circular loop of condescending responses in the Xfinity App (also [Edited: "Language"]) and was able to schedule an appointment for 10am Saturday.  On Monday, while at work,  I received two phone calls. One, automated, asking if our issue was resolved. The second was a live person who said that some plant maintenance had been done, and wanted to know if my issue was resolved?  I told him I would not know until I got home and that if it was, I would cancel the appointment.   The issue was not resolved.  I have proof in the form of an ongoing ping test.  On Saturday morning nobody showed up.  I started an online chat.  The agent was Kumar who was helpful and courteous.  Kumar said the appointment was cancelled by the technician because the service work was complete.  Kumar offered to schedule the next available technician and give us an account credit.  After getting things scheduled, I checked my account and found a generous credit of $19.53. 

Seriously looking for alternative Service
