Fnb doesn’t want to help

My account was upgraded without me completing the upgrade process and now I learn I have a Cheque account yet when you review my account it clearly states it’s not a cheque account, to complete upgrade I had to submit kyc docs and I did not have it handy, this was some months or possibly over a year ago, I have been charged for a Cheque account yet I was not aware that my account has been upgraded to a Cheque account
