Bad Service from Capitec regarding Vehicle disc renewals

I renewed my 2 vehicle license discs on 23 September 2025 through the Capitec banking app. I only received 1 disc so far. 17 days later and I am still waiting for my other vehicle disc. I have been to the Capitec branches on numerous occasions, but no one can tell me where my other license is. I tried to contact RTMC but no response from them. I am refusing to pay for a reprint of my vehicle license disc as I already paid for a service that I didn't receive. This is unacceptable.
