Oh, no! Sorry to hear that, Miles. Well, as you can see for my signature, all went well. We got Openreach and they bent over backwards to install. I really cannot fault them, they're a brilliant company!

Finally installed this morning...took the guys just an hour to do.
They were from the Kelly Group, but I have to say they did a decent job of running the cables nicely and tidying up afterwards.

It's so nice to have decent speeds again (500/75) after my year with 36/10...not that anyone else in my house will notice
