FNB *******ly billing clients

FNB *******ly and without authorisation changed my business account type (First Zero to Gold), leading to additional ******* bank charges.

I have logged messages for clarification, complaints and escalations for 3 weeks, and still no response from FNB. I receive no messages or emails since logging my concerns.

I am still being billed, yet FNB does not respond or act on my queries.
