Frustrated with an almost none effecient car we just purchased

I am in distress due to a red BMW 2012 model that I purchased through Westbank from this dealership I was assured that the car passed the test at traffic department however I doubt because from the very 1st week of purchase problems started:

15 june 2020 the car was delivered -19 june 2020 handle broke -23 June 2020 car taken for repair and alignment-18 july 2020 the car couldn't open the door(not responding to mobilizer nor manual locking for 2 days) 20 july 2020 they came n fetched the car for repair -21 july 2020 brought the car back -22 July 2020 the car couldn't start on it's own needed to be jumpstarted -24 july 2020 we took the car back to the garage they checked n said is the water tank n they changed it. Our desire as a couple was clear that we want a new car due to the unbearable condition of this car, we deliberated with the sales man who sold the car to us however when we thought we have reached consensus about getting a replacement he threatened me that I will be taken to credit bureau if we take a new car. We then ended up with same car. -29 july 2020 water pipe clamp broke just where they were fixing it on the 24th. I then called the sales man: Louis Seonyana who claimed to refund me from his pocket for the clamp I replaced at R900 to date he hasn't honored his word.

We bought a 2nd hand car knowingly that it is not knew but this 1 deserved to be s****ped or at least sold at a lway esser price than what we for it for.

Lichtenburg motors we can't pay for a car we are unable to use and enjoy . We need a replacement of a good condition 2nd hand car Westbank please intervene
