E2save Cashback/ O2 Retentions Upgrade

Quentin

When you speak to o2 retentions, whatever deal you agree to takes effect immediately (or the next day), (ie, no notice is required), so you aren't really having to pay an extra month on the original contract.

Also if, (which happens in some cases), you only require the bill that comes at the start of month 12 for cashback purposes, then you can make a little hay by doing the tariff upgrade deal as soon as the bill is to hand, as o2 again just implement the change immediately without waiting for the end of the original minimum period.
