I am very disappointed with FNB

I am very disappointed with FNB. They offered me a Premier Cheque account in 2017, which i requested them to close because i was under debt review could not get any benefits on. When i finished my debt review i went back to FNB to open a new cheque account i was told i have a dormant cheque account that has a balance that has been accruing due to bank charges. The consultant couldn't help with the query and said i need to call the call center. The call center referred me back to the branch i went to a different branch with no luck. I wrote a complaint on the FNB website over a week ago also no response.
