My account has been paid in full and I havent used it in 3 months yet they still add service fees now they want to hand me over for R138.91 in serivce fees which I refuse to pay because I dont use my card anymore! pahtetic! I buy all my groceries and clothes from woolworths cash monthly and over R138.91 service fees I will not be returning! Checkers will be getting my money from now on.
