Vehicle License Registration headache

I bought my car at Webuycars Midstream branch beginning of February 2023 and I was charged and paid around R2 000 for license and registration but up to date I haven’t received my license disc, I was assisted by Jean Van Der Schyff and Nikita Robinson. End of March 2023 I received a text message from Webuycars Midstream licencing department that the license department did not issue a license disc due to roadworthy required, I contacted the sale person, Jean Van Der Schyff who said Webuycars Midstream licencing department took long to process the registration and I should bring my car back at Webuycars Midstream branch so that the car can go for a roadworthy test again or alternatively I can take the car to the nearest Dekra centre and he will write an order for me to take it to Dekra centre and after the test I should forward a roadworthy certificate to him, I choose the second option and he wrote me an order and I took my car for roadworthy test and after the test I forwarded both Jean Van Der Schyff and Nikita Robinson the roadworthy certificate so that they can forward the roadworthy certificate to Webuycars Midstream licencing department as requested.

In May 2023 I went to Webuycars Midstream licencing department to collect the license disc however there was no license disc and the lady at Webuycars Midstream licencing department said they didn’t receive the roadworthy certificate from both Jean Van Der Schyff and Nikita Robinson and that I should follow up with Jean Van Der Schyff, I followed up with Jean Van Der Schyff via WhatsApp to no reply, my roadworthy certificate end up expiring without license disc being issued.

I am so frustrated as the license disc that came with the car is due to expire and my license disc still not issued.
