Disgust of car bought

Got in contact with them from Ireland regarding a car on their website for my daughter's 18th birthday present. Bought car, their card machine did not work after a week I have told them that my daughter has my international card for the transaction, day of purchase had to make an international transfer instead that took 5+ days to clear, my daughter drove from Rustenburg, she had to return another day. I had to pay again for someone to take her there to collect car ontop of additional international bank fees!! Car broke down half way to Rustenburg, overheated and radiator leak and head gasket blown. This is pathetic. I have send a WhatsApp, now suddenly unanswered weeks on end. Before sale I received daily WhatsApp messages. Who is responsible for this now?? So much additional expenses for me and its 3 weeks later and my daughter still have not been able to put a mile on her own car as its still being repaired on my own expenses. Beware of cars being sold. Utterly disgusted.
