Pathetic service

I have never experienced this kind of behavior from a business. I have waited almost 2 months for my part to arrive only to be told on the day of it supposed to be arriving that i have to wait at least another 2 weeks possibly to get it fixed?? I am without a vehicle, i have to get to work, i have a son whom is on the spectrum that i have to take to school and pick up, i have to take him for his Occupational therapy, speech therapy, doctor's appointments etc.. Only response from Hyundai / Kia is sorry, nothing they can do about it???? I have not taken my son to any of his additional classes for so long, but.. Hey.. They said sorry. I have been a loyal Hyundai car owner, have always had Hyundai as my go to car, i will not be doing that anymore, Kim the supervisor has been helpful, but evidently the Dealer Principle, parts managers are nothing short of appalling and evidently dont know how to run the business. Thank you very much Hyundai / Kia Fourways for making my life Hell even though i have paid for the parts etc.. I will never recommend this dealership or brand to anybody ever again.
