Disputable service from FNB and FirstRand bank, sickening!!!

I’m assuming the account listed under my credit rating is that of a subsidiary (FNB) as I have no affiliation to First Rand Bank directly. I bank with FNB and have been for many years, I recently started paying close attention to my credit score and ratings and discovered that there was an outstanding account under FirstRand bank that I have been trying to dispute. I have logged complaints with FNB for months now, all I keep getting are automated responses and no resolution to date. I am sickened from the lack of customer care/service and experience that I have received from this organisation. The bank charges are not worth the paper that they are printed on. Quiet frankly, smaller banks that still have capacity to focus on their customers, such as Capitec, are where I’m taking my business.

I want a resolution to this NOW, it is affecting my credit record!!!
