price change opt out question.

[#1]

I have received an email telling me I can opt out with no penalty fees because the price is going up.
Can I leave and then rejoin as a new customer enjoying the new customer benefits or do I have to leave and go to a different provider?
I'd like to do this as fibre has recently been implemented in my area and I'd like to go with that.
thanks

I'd suspect you'd have to cease everything, which would cost way more than you'd save.
Best to ring customer options

phoned the customer options team - all sorted with a new contract now. Upgraded from broadband to fibre and its actually costing less!
