Product change timelines

[#1]

Morning PlusNet,
I initiated a product change on the 10th March and received an email saying it would process by the 11th March. However nothing changed and I see now there was some error which seems to have been dealt with. Can you give any clue as to how long the change is now likely to take?

Maybe asking the question on a Saturday wasn't a good idea...Anyone able to tell me when I should expect my speed increase to be processed?

Ta.
