Poor service from FNB Navcar and Private Banking

I used FNB’s Navcar to renew my car license disk and then canceled it as they said documents not received. I then tried to renew it and sent an email to the address provided, then sent a follow and there after several follow ups to Navcar and my private banker. More than a month later private bank comes back to without any solutions. Then speak to the private banking manager who attempts to help. I had to apply for licence renewal again and he tell me it was successfully processed. Two days I get a message that I need to send documents. When I app**** through the app it asked me to upload my docs which I did. I sent a screenshot to the private banking manager who reverted saying he contacted Navcar and they said I must ignore they have the documents. Then today they cancelled the application due to no documents. I sent a screenshot to the private banking manager and he reverts there was an issue between the app and the service provider. Gosh. What happened to UAT, do changes get implemented without testing these day by large corporates. I was then asked to apply again. My licence expires on 31 October and I have been fighting with FNB since 7 October to get this right. As private banking was no help either so I am paying for private banking and Navcar with no service, what is the point. I will now be moving my banking portfolio to another bank and I have said Navcar must pay back my monthly fee as they did nothing for me. Though I am not expecting much.
