FNB bad customer support to downgrade your account

FNB will upgrade your cards very quickly when they contact you.but when you are not happy with the benefits and ask for them to downgrade you its over a month and it has still not been resolved.i have contacted them multiple times where i get told i am just wait for a response.they have currently only downgraded my cheque card and not my credit card.which i am paying higher fees now.i have asked to be put exactly the way i was before they upgraded me. i think FNB does this so they can let you pay higher fees.
