I had issues too that they sent a tech support out for while warning me "If they find it's your fault, you will be assessed a charge". The tech came out, climbed my local pole and then went down the street and climbed another one. He said it was a busted port and he moved me to a new one, and put in a service request to upgrade as it was out of ports.
CenturyLink sends me a bill for maintenance. After tons of back and forth I got to the point where I said "So can you state for the record since I'm recording this phone call, that I the customer should have climbed the telephone pole to remedy the issue".
After that he finally decides to get in touch with the fiber contractor they use who emphasized it was no fault of my own and they cleared the charge.
Some pretty interesting stuff that hits home for me. I was diagnosed with lung cancer in 2021 and I had an army of family and friends trying to find me a covid vaccine when it was only being offered to seniors 65+. Finally had a friend volunteering at a vaccination clinic which had some leftover and called me in. I wouldn't have considered it might impact my cancer treatment outside of them being unable to operate if I had covid.
There's a marked contrast between vaccinated and unvaccinated survival rates, and they pretty extensively tested and ruled out additional mechanisms they thought may be influencing their observations.
