Nedbank kicking a customer of 25 years + in the teeth!!

I am a customer for over 25 years with Nedbank and have my credit card, current account, bond and motor finance with them. In 2019 I started having serious issues with Vodacom which due to their internal maladministration stated I owed them a amount in error from an early cancelation that was ironically due to their poor service. This bad payment is now in error on my credit profile.

Fast forward to 2022 and I app**** for a home loan on 2022-04-19 only to be given a serious runaround by Nedbank (more specifically my personal banker Lionel Johnson). Yes, I have a personal banker and pay extra for that "service". In short when I finally after having to battle and a month later I got some feedback out of Lionel he told me that my loan is declined due to the Vodacom bad payment. This even though I provided correspondence and proof of payment that can easily be verified as the payment was done through Nedbank. The treatment I got through Vodacom, Nedbank "Professional" Banking is shocking and I would advise anybody to think twice before attempting to do business through these businesses that do not value customers of long standing.
