Unstable Internet

I’ve been trying for WEEKS to get my internet working - I have fine speed and updated hardware, but my stability is all over the place. It’s so bad, I can’t even take a video call from home (which I need to do for work.) 

We had a tech come out to look at the lines (after A TON of trying to get through Xfinity’s automated system) and he said the signals coming into our house were too strong. He put a maintenance ticket in and said it would be resolved within 10 days - but here we are almost a month later. 

I’ve tried to get in contact with Customer Service and it’s IMPOSSIBLE!! Even the landing page that has you schedule a callback to chat with a representative doesn’t work (and now I have a suspicion that it might not even be a real page…)
