Pathetic service

I app**** & paid for my car licence disk renewal through the FNB app (Nav car) on the 2nd Nov and a month later I still haven't received my licence disk. I was told that it is a 5 day turn around time for Gauteng but its been 4 weeks. I have called them several times and sent many email requesting atleast an invoice to prove that I have initiated the process as proof for the traffic officers on the road daily but haven't received anything. I have asked for the escalation path and even a cancellation guide but nothing is being done. This is pathetic service and I regret using this avenue, if I had gone to the post office I would've paid less and would've received it the same time.
