I've had an ongoing issue with my internet for several months now, and my main experience with them is that they don't even show up. I had one Openreach engineer not turn up back in May when I had taken a day off work just for this. The same issue has been an ongoing problem, and 2 weeks ago, another engineer said the issue was underground and would involve digging up my garden and the pavement outside to resolve it. I told them to go ahead. After many instances of chasing up with BT (don't ask) about what was happening, I was told Openreach were coming to do the work yesterday, I even had a phone call the day before to confirm. Guess what, they didn't turn up, and BT's response, even when escalated to management, seems to be, we really hope they turn up soon. Absolutely useless from both companies.
