Ok, at this point I've had enough.
Anyone in the UK looking at Lila Connect for your Fibre broadband - they are incapable of listening to requests to use Email to communicate. They will just relentlessly ring you from phone numbers without identifiers.
They've had a £50 fee for 5 months with no movement, and there is no timeline on when it can be installed.
I asked to swap package, they cancelled my order and wanted me to call them
Again, I said I want emails not calls.
They called.
Avoid.
