Superb. I dumped my existing ISP (Zen Internet) after they couldn't/wouldn't sort what was clearly an Openreach-induced cabinet fault resulting in a completely dead copper pair. Migrated to A&A advising them that the line wasn't working - they got it sorted within 72 hours of the transfer. They have the right sort of relationship with Openreach to get stuff done, and also don't patronise their more technically aware customers or insist on reading from a call centre script (or insist you plug in some dreadful piece of crud plastic childrens' router to test the line). Was particularly helpful to have a single, named contact who dealt with the whole thing from start to finish.
