Very bad service from Eastvaal motors Witbank

I took my car for service, then they said there is oil leak on my car so they need to strip the car and that can take about two weeks mind you I never saw any oil stains where I pack my car, but I agreed cause I thought they know best, they did not communicate with me for the duration that my car was with them, two weeks n few days later they said I can come and fetch it, I started hearing some strange noise every time I drive over a speed hump at first I thought maybe it’s all in my mind but I gave my brother the car n he also picked up that there is something loose, I called them to inform them about the issue they said I must bring the car, I’m hear now it seems like I won’t get any help some guy drove the car n he said he doesn’t hear any funny sound but they will check it out I bought a brand new car cause I was avoiding spending money on mechanics every month n I’m just a girl I don’t know much about cars so I’m so shattered cause it seems like these people will s**** my car😭😭😭there was no oil leak on my car it was just their way of claiming from warranty
