Poor Customer Service, theft, rudeness, overcharging, ************* personnel

I took my car in for service of 165000 km on 23 September 2019 and left the car so they can replace the clutch as well. They took their time with the clutch, giving excuses that other parts needed replacing also and revising quotes. Then on the 11 October 2019 the service center lady calls me and tells me that the parts have arrived and I should have the car the next day. The next day comes and goes without even a call from KiA to update me. Come Monday the lady calls and asks if I have a spare key because they had lost my key, but the car was ready and needed to be tested and washed. From the they go quiet till I call them on Wednesday 16 October 2019, where they gave the workshop guy to rudely tell me I can’t come fetch my car, they have ordered they so I’ll have to wait for their call. On Friday I sent my Mother to go fetch the car, only to find the key was not even there. What do they expect me to drive in the meantime? They have kept my car for 4 weeks now. The workshop man is very rude and keeps lying. I want my new set of keys and if they have to change the whole key starter, they must do that. That’s not my problem. Kia also is very ***********, they duplicated items on the service quote.
