Re: I once had fun with Talk Talk...
Before the split with BT and OpenReach, I had a related issue with BT at one property we moved into. I phoned BT and asked them to make the phone line live in the property, but they said the property had never had a phone line into it. I explained that there was a telegraph pole outside with a line coming into the property into a BT master socket. It even had a continuous tone indicating it was hooked up. But no they said, our property wasn't even on their records, was it a new build? No, it was around 80 years old! Anyway, they booked an engineer to install a phone line.
He arrived expecting to run cable etc but was surprised to see we already had a BT line. A few tweaks and we were up and running.
In my experience all telecoms/internet providers rate on a scale between very incompetent to moderately incompetent. And I've dealt with most of them over the years.
