Breach of Contract and Appalling Customer Service

Chery J3 was giving us issues. It refused to start at random times.In October we called the Chery road side assistance, they sent someone to come and assist us. The car still didn't start after the guys tried numerous times which then resulted in the car having been towed to the Chery Germiston service dealer.The car stayed there for two days then they called us to come collect it as they said they didn't find any faults. a day after the collection the same issue persisted.I then called the Germiston dealer they said there was nothing they could do as they didn't find any fault.I then asked that they book it in we will not leave until they issue happens in their presence. we went there on 11 Nov and they saw the issue then they booked the car in.Week later I didn't get any feedback from them then called to ask for feedback they said parts were ordered and we should received the car on the week of 25 Nov.No car was received on that date, called to get feedback, parts had not been delivered and they could not give me a date of delivery.called Chery SA and they gave me a date of delivery however no commitment for the date of when the dealer will get it.Breach of warranty
