Ford Umhlanga MUST FALL!!!!!!

I Kenneth Sethunya have purchased a brand new ford Everest 2019 Model from ford Umhlanga. I've been saving up for a car for more then 6 years, finally managed to buy one brand new and it wasn't a pleasant experience with this dealership. i spoken to Khanyisile Mkhenyane arranging for set up my deal. everything went through successfully. i arrived on the 20JUN19 to collect my new car drove it home and released the aircon was not working. My Family and i drove the next day to ford umhlanga to report this matter. we have a huge argument when they wanted to give me a ford fiesta as a courtesy car. i was going on a holiday and couldn't use such a small car. i then threatened to cancel the deal and then was given an everest by the branch while my aircon is being sorted out. on the 24 JUNE 19 my car was given back to me advising the aircon has been fixed with no explanation. on the 13 JULY 19 my aircon stop working again. i had to send the car back to ford. and i asked for the branch to please replace this car cause i didn't want to go through this problem again back and forth. The sales Manager (Gerald botha) advised this wont happen. i asked to cancel the deal. he said rudely that wont happen. my car was taken in and i was given a ford fiesta again. I then spoke to the dealer principal about this matter and he had the same stinking attitude he made me feel small as a person telling me about customers who paid 800k and he helped them with whatever car he got. and he doesnt makes car he sells cars. i purchased this vehicle for my family and we planned to go on holiday with a family of 6. how where we supposed to use a ford fiesta ???????????????? i then phoned ford south africa nothing much could be done there. i then contacted the bank to cancel this deal. this is a brand new car why would the aircon not be working? or me going back and forth with this disgusting dealership. today is the 05aug19 my car is still in the dealership no contact has been made or any updates, i don't have a car to use and the branch doesn't care. this is not fair to treat people. the bank took the first installment for the car. what car ? because im paying for a car that's at the shop. i refuse to pay for this car and let it get repossessed from me. i hope people read and understand that this suppose to be a professional working environment.
