Goldwagen City suburban selling faulty parts

I don't even know where to begin with these people at Goldwagen joburg city suburban They sold me a faulty part and now they are telling me that I have to wait 2weeks for them to claim. The rude sales guy even told me to put him on social media he doesn't care. Are you guys running a ****a shop or a spares shop. I can't wait two weeks cause of your incompetence. My advice buy spares from any other Goldwagen and not 23 mooi Street in Johannesburg
