AA Good. It took them six months to get a totally incompetent Openreach to finally sort my underground fault. I moved to save £10 per month with Freeola who I had previously used before they did FTTC and knew of their good customer service. I want to keep my line with Pulse8 if I can - £13 per month and 1ppm with no connection fee and per second billing.
If I am forced to jump, IDNet looks attractive with decent service and probably save a bit more. I am aware they also do line and calls around the same price as Pulse8, but putting both with them looks like I would end unbundled away from a BT line again, Which I don't really want. Service was OK, but a pain whe BT pretend they cannot trace the number when you want a check of some sort, though they can trace it fast enough for a repair or sale. Would go all-in with Pulse8 in a flash again if not for the unbundling.
