I've been with AA for a very long time now across multiple addresses and now different services.

I've personally found them to be very helpful on the occasion where support has been required, quick to reply and very technically competent. No reading from a script or having to explain the issue multiple times.

Anything that has meant Openreach has had to fix has also been dealt with swiftly.

For sure there maybe cheaper service out there, but you get what you pay for when it comes to support. So for me, the cost is worth it.
