Getting billed for upgrade when upgrade not installed.

[grahamm1]

My contract does not expire until next month. I called customer services to see what was available and placed an order to "upgrade" to Full Fibre 100.
A couple of weeks ago Openreach tried to do the fibre install, but could not complete the work as a hoist was needed to access the pole. They have arranged to come back in a few weeks time (hoists are in short supply, apparently).
In the mean time I've received my bill which is for Full Fibre 100 (which I've not yet got).
Is that correct or should I still be getting billed for my original contract?

Hi @grahamm1, thanks for your post. 

You should be charged for your original package until the new deal is active. The delay in your connection has caused the billing to change over on the original agreed connection date. 

Once you're connected on the Fibre 100 the difference in the charge can be refunded. 

Cheers
