Very bad service from Wesbank license discs renewal service

I've renewed license discs for my vehicles with Wesbank via fnb app on the 13th November. Told that license discs renewed and the courier will contact me for delivery but till to date no one has contacted or communicated anything. I have called Wesbank numerous times only to be told that my matter has been escalated and will be contacted before the end of the day. Everyday same story with no one calling me back. I am so frustrated sitting with 3 vehicles without license discs. I'm suffering for trusting the bank that was supposed to serve me.
