I've just received my MAC no for migrating away from Plusnet. My next billing
date is 15 August, if I migrate away before that date say 14 August I take it
I wont be billed on the 15th as I pay a mth in advance. But leaving after the 15th
I would be billed, also could I claim back anything if I left after the 15th but
before the next billing date next mth.
There is a 30 day notice period on your account which you will need to pay for regardless of when you choose to move. Asking for your mac code does not mean you have given notice for your account necessarily.
