(a) in the case of a variation that increases the credit charge under the contract, or increases the amount of, or abridges the time for payment of, the amount standing to the debit of the account--until a period that is not shorter than 2 billing cycles has elapsed after notice of the variation has been given to the debtor in writing; or
(b) in the case of any other variation--until a period of--
(i) at least 7 clear days; or
(ii) where the contract provides for a period of notice of the variation, that period;
whichever is the longer has elapsed after notice of the variation has been given to the debtor in writing.
