Kia promise is hopeless promise

Worst sales people dealt with. Theo and Moses are just the worst to deal with. Worst experience purchasing a car ever. From delaying the purchase, to delays in receiving my inatis papers, spare keys, and number plates. as the vehicle was fully paid for but the excuses after they received their money was just beyond me. No alarm in vehicle, and was not declared to me. Vehicle had Dekra report but had to tell sales guys what was wrong with vehicle. They attempted to fix, but what shoddy work from Kia. Asked to speak to dealer principle and was given a loan car for two days but nothing was actually repaired on vehicle and was told that i should drive the car for few more days to see if problem goes away as this is what their workshop told them. I own many vehicles and never ever heard such bull in my life. I guess im stuck with a vehicle for a while with extra repairs because i bought it out of desperation thinking Kia reliability but will never trust Kia ever again.
