Line down/Faulty wire

I called 4 different times and spoke to 4 different representatives who would not help me solve the issue related to the exterior wiring/telephone pole outside that seems to be causing my WiFi issues and instead want to charge $100 to send a technician out since I did not have them professionally set up my modem/gateway. After explaining countless time I just moved to this rental property and did not need professional setup as the owners already had that done when they lived here and that I just needed them to fix my gateway being “unresponsive” even though I followed every instruction to reset it and the outage map says no outage it still is not working. I have had Xfinity WiFi setup for 2 weeks now and never had an issue until today when a neighbor must have had an outage or issue and I was in my backyard STILL USING THE WIFI when a technician came and climbed the telephone pole where my exterior wires connect to from my property and when I went back inside AFTER he left the WiFi was no longer working. I explained this over and over again over the phone and they just kept saying pay the $100 to have a technician come out but why would I be responsible if the technician that was there earlier in the day caused the issue when my WiFi was working fine before he was there?! To top it off my neighbors said they are having the same issue as of this afternoon!! Not sure if anyone else had similar issues with this company but I am very disappointed in the way Xfinity wants to rip its customers off for problems their own technicians caused. It also appears a wire is down from the same pole in the alley next to my house so I’m not going to pay $100 to fix an issue I had no responsibility in causing. Really hope they resolve this issue sooner than later because as a paying customer it’s ridiculous to get ripped off when we pay for the service they claim is working but is not
