NAV Car Disappointment - where is my credit?

Hi Guys, whilst I love and appreciate the Nav car offerings, I am highly disappointed in the service and the outcomes I requested and paid for the license renewal. Everything went well saying it was with the license department and being processed for renewel and that all documents are in order. etc, and I could expect it to come soon. Suddenly I got a notification saying the process is declined due to another existing vehicle license disc being expired.. heres the problems:

1 - FNB does not allow me to renew both discs at the same time? So how would I be able to use this feature if I can only do one at a time and be charged delivery fees individually. 2 - CAN I HAVE MY MONEY BACK??! how on earth do you take the money and cancel the transaction at the last minute and not credit me? 3 - the app still says its pending but its blocked.

HOW ON EARTH am I meant to progress with this? I cannot go to the license department for renewal if you cannot give me the money back?

When I go to the license department they will undoubtedly want to renew both at the same time. I have emailed twice on the app for this enquiry - no one has responded or contacted me with answers

Basically this is the same as paying a builder for a complete job but then he walks away with all your money because the lawn wasnt cut in the area he is supposed to build.
