WOODMEAD HYUNDAI HAS THE WORST SERVICE FOR ANYONE WANTING TO PURCHASE A NEW CAR

I am very displeased with Hyundai Woodmead. Its as if they don't care about their customers. I bought myself a new car from their branch in January and that was the biggest mistake ever as i was the one who was constantly running to them to sort out issues or receive feedback, Its as if i had to help myself because they don't bother with correspondence of some sort. Every time i raise my concerns, it was handled by the dealer principle however the matters were never fully resolved. I am now a few months down the line, and i still have not received my spare keys, service book, or money that is owed to me since January. Every time i message the sales or floor manager (Solomon or Tinus) i get the response of we will sort this out. A couple of days pass and i am running back to them asking for updates. Today i respond that i am going to email the dealer principle as i am not satisfied with the non feedback from Hyundai, and i get a thumbs up. Its as if my issue doesn't matter and no one wants t escalate my problem and sort it out. I have had enough as this is immature behavior and pathetic service from the WOODMEAD branch. I would like to have my issue sorted and never return to that branch ever again. I have all the previous correspondence from past complaints and issues regarding purchasing a car that was faulty to begin with, and although it has been sorted out now, there are other problems not yet sorted out.
