Pathetic service - No contact from business banker

I had opened a business account with FNB last year July. Due to the poor service received I had stopped using the FNB business account and had not received a single email or call from my business banker. I had asked Anastasia numerous times to get my business banker to call me but did not receive a single call. I had to constantly follow up. I am receiving emails from some attorneys for a mere R300 in service fees that have piled up. I had asked Anastasia for the account to be closed last year. Why did my business banker not call me ever to even ask why the account was dormant??? I want the service fees to be reversed and the fees to be reversed as there was no service provided.
