They finally fixed my outage issues... here's what they did
After not showing up for my first appointment last week or even calling to day they couldn't make it (I had to call them), they actually showed up to the scheduled appointment today, which was a big surprise for me. I was beginning to think Quantum technicians didn't exist, but they do! After digging through my yard they had found a splice in the cable that they say has gotten wet and corroded over time. So they redid the splice, put it inside a short PVC pipe and filled it with silicone so it can't get waterlogged again (hopefully). I had to show them the route the cable was buried as they didn't have a locator/tracer. And the wire is so thin that I doubt there's tracer wire inside the sheath anyway. Hey it's cheaper (for them) that way!
They also told me that they were short staffed and that there are so many new installs because ATT is offering "great deals". So that's why it's taking weeks to get a tech out to your place. The ATT deals are just TOO GOOD! /s They said they are working mandatory 6 days a week now.
Anyway, it's all back up and running 3.2gbps up and down. Just make sure that if anyone makes splices in your cables, they secure them with silicone and not just leave it open to the elements like the original tech who installed me apparently did.
