Terribly bad and slow service form Webuycars and platinum auto durban

WeBuyCars Durban Springfield sold me a car that had a pre-existing condition I'm not sure how the dekra check did not pick it up but I feel this was covered up. after a few months of owning the vehicle I picked up the car had a water leak which was leaking on the inside wetting the car floor which was odd for a fairly new vehicle, i made the sales advisor aware and was advised to log it with their customer service team, to mention takes forever to respond they advised me to take the car to Platinum auto Durban where I was advised it will be diagnosed and fixed within one week, no courtesy car was provided and I left the car with them the beginning of February!!! this workshop is taking forever, it went in for 1 thing, which took over a month to get fixed however now they broke something and its sitting with them. After numerous follow ups another month passed, i receive no calls or updates i have to constantly call to find out what's taking so long and all i get is excuses and empty promises after many calls and me trying to log a complaint the beginning of April the owner calls and advised his taken over and there's some progress which is taking another month while following up i find out they outsourced the job as they could not fix it, furthermore I find out it was outsourced to a non rmi workshop. which is not right, the rmi complaints department advised they can't pick up platinum auto on their data base I asked for a picture of their certificate but they did not send it there's no sense of urgency or promise with this workshop, what I was advised was a 1 week job has turned into a 3-month long night mare, they have no care of the inconvenience caused? neither any sense of urgency, we buy cars have not intervened in any way what so ever I regret ever buying this car from them
