Pathetic customer service on cash purchase.

I purchased a vehicle of over R210000 in cash from webuycars in june 2024. My vehicle license disc has now expired in Marxh 2025 and upon attempting to renew, i was advised by licensing dept that my vehicle requires roadworthy testing before new disc can be issued. I paid over R2000 for licensing fee to webuycars yet they couldnt do roadworthy when doing change of ownership. No representative at webuycars had advised me that the exhorbitant fee is only for change of ownership. Poor customer service and poor staff ettiquette. All these t's & c's need to be explained to customers. You push us to "just sign here" on a million pages on an ipad to get the sale finalised. I need an answer from webuycars. This is a huge inconvenience and a very frustrating situation to be put in without my knowledge.
