Worst service - No cards delivered in time, yet I am paying for this service

I am a Platinum client with Nedbank. As part of my agreement, I get the benefit of having cards delivered to me for free and not paying additional for it (included in my monthly fees). However, my cards all expired between the end of February and the end of March 2022. I received sms' which asked me to reply in order to have my cards delivered. I rep**** within the hour and this was well in advance of my cards expiring. To date, I have only received my cheque account card (2 months late) and the other cards did not arrive. When I speak to Nedbank, I get the response that the courier will contact me, which they don't. I have escalated my problem to the complaints line and received very abrubt feedback stating my cards are with the couriers (no appology for the delay and no confirmation regarding which cards). I have changed my service provider now due to this lack of service. How does Nedbank expect me to use this service if I don't even have cards or explanations.
