OK. We've all but binned BT off now.
ZEN were tried but ended up being completely hopeless, website and 2 chat humans telling us false information, then the sales guy saying it's actually not available. Hollow apologies, so they 100% won't get our recommendation.
We have looked into MS3 (not sure why, looking at the reviews) but gone directly with a service provider.
First try was Open-Fibre. Ordered the Full Fibre, but they were dog slow responding to questions and broke immediate promises to send us information / paperwork. Cancelled.
Tried Infinics, clearly pointless as they still haven't responded to my email. Binned off.
Finally "Squirrel". Super fast responses, answers to all questions, Zero to do with BT or Openreach anywhere in the chain apparently. £35 a month full pelt 1Gbit.
Ordered.
Insane to have to go through all this in 2023
