I requested to close my fusion account on 5 June 2023 which was not done, now I am being handed over to the credit bureau for unpaid charges. Upon visiting the Mall@Reds branch, it turned out that the branch is unable to assist and work through the same call centre the clients do. The first call consultant simply abandoned the call. The second consultant was very rude and transferred the call without hearing the request. The third consultant claimed communication that was not received. The two consultants which responded to the original and follow up requests to close the account were not available and an email had to be sent. The branch manager was not available. I walked out of there with no assistance toward resolution. Don't bank with FNB. They will ruin your credit status based on their own incompetence and lack of action.
