Product Change Full fiber - Not Taken an effect

[#1]

Hi,

I opted for an upgrade to service from 300Mb's to 500Mb's. The confirmation mentioned it to take place today. But nothing has happend, im still only getting 300. 

When i log into my account the contract hasn't changed. And i get:

An error has occurred

You can't change your products for the moment, you already have a product change in progress.

As "today" hasn't ended yet (so there's still time), or typically connection changes occur in the early hours of the following morning, wait until say 8am tomorrow and try doing a power off of the Openreach ONT, count to ten, and then power back on, to force a re-sync of your connection with it's new settings, then re-test your connection speeds using an ethernet connected computer or laptop.
