My personal account opened as a business account

I have been trying to apply for a overdraft on my savvy bundle account online and i have been told my account reflects as a business account and thus the system does not allow me to have overdraft, i must consult my branch at Fox street in Johannesburg. This morning i went there and i'm told by a banker called Thapelo that my account on their side appears as a personal account. We called the overdraft department of nedbank and my account on their side appears as a business account. I have not been able to find any solution regarding what is happening on my account and i'm presently unable to apply for the overdraft since there system still pick my account up as a business account. i also wonder if my bank charges on this account have been of a personal account or a business account as i believe they charges are not the same.This has been an inconvenience since the problem is with the bank and no one seems to be able to resolve the situation even at my branch.
