I've been with AA ISP for just over a year. They were excellent at getting all of the services sorted for piping FTTP to my previous house.
Recently moved to another house and did a migration. Had a minor hiccup, but this was all sorted and did not affect setup / service.
They were also good enough to extend my usage cap on a one off once, which was a nice gesture.
Not hugely keen on the WiFi on the Technicolor router as it doesn't seem to play nice with one of my phones and clashes with a BT Hub we have as an extender. This isn't really an AA problem, but as it's the router they ship, would be nice to have some more documentation out there one day.
