Less than ideal but on par with my expectations of BT unfortunately.Not BT's fault. It's because you moved your telephone to another provider.
I would have agreed were it not for the fact that;
1 BT's ordering system acknowledging that my line was with another provider at the point of order,
2 Several calls with BT confirming that my number would not change in moving from Sky and that this was a common migration, and the two activities could be completed in parallel
3 10 days passing between ordering and having the install appointment scheduled and BT realising that there was a disconnect,
4 receiving confirmation that my equipment is in transit and will arrive on Wednesday
You are of course correct in admonishing me for now doubting what I had been told several times and I will be less critical of incompetence in future.
