Ive just had my cca request returned which is apparently enforcable

but i have just been informed by my wife that we was paying something called "credit care" which we cancelled in 2007, but it doesnt say anything about it on the agreement

We have paid nearly £2000 of these payments according to the statements we can find 2005 to 2007. We first had the card in 2002 but cant remember signing for any credit care payments.
Also the account number changed in 2005 so the account number we have now is different from the one on the agreement
Has anyone else had credit care payments made, can they be claimed back?
