Hyundai Lephalahle dispute on payment of alternato

I bought a Hyundai H*** model with 92000km from Hyundai Lephalahle. Upon delivery, there was an immediate problematic alternator. The vehicle was sent back the workshop where Rassie exchanged the alternator with an old H100, which were stripped, for spares. Assurance was given to me that the alternator is in good condition. <br> Rassie, in the employment of Hyundai, Lephalahle at the time of the incident (Cell: ***) will confirm this exchange. Rassie was the mechanic at Hyundai Lephalala. Unfortunately, this alternator did not last and had to be replaced in December 2015. I contacted Hyundai Lephalahle in December 2015 to inform and confirm the used alternator installed originally broke down. I spoke to Hendrik confirmed that I can either repair, replace or Hyundai Lephalahl will refund me. I shortly after this conversation replaced the alternator at Rautenbach Auto, Sasolburg . The alternator was replaced because it was irreparable. I contacted Hendrik once again. The original confirmation of replacing/repairing of said alternator was not honoured. I was informed that now I have to take the vehicle to a Hyundai branch and Hyundai Lephalahle refuse to pay
