Bad customer service

I rented a car from avis (budget) Friday 30 August group G BMW 318i white. The vehicle was rented from O R Thambo international Airport. I then extended my rental to the 11 September on my way from portchefstroom the cars engine light comes on I then quickly check the cars on board system and I realized that the car is 2000 kilometers past there services date ( let me be clear I am not responsible to check if you have service your car our not) I call your customer services center spoke to a lady she as**** me that the calls is recorded and I will be getting help I advise her that I can go to portchefstroom and change the car cause I was afraid this car will not make it to JHB. She call the branch in portchefstroom so I can collect a different car I then get to the branch 8 was then told that I must wait for the car to get wash be for can get it ( I have a flyde to catsh from JHB to Durban and me nd my wife we must it. The portchefstroom branch the service was very poor. I drove the car to O R Thambo international Airport and returned the car my experience there was even worst I managed to exchange the car it was replace with another BMW 318i that also have past the service date I had to drive that car to Durban cause thanks to avis and budget me nd my wife missed our flight and drove that car to Durban it was a very bad experience I have extended my rental till next week Wednesday with the wonderful service at the UMHLANGA branch in durban I got assistance. The Branch manager at O R Thambo have very bad customer service s****s and have no way 9f of dealing with customers I have been renting with avis and budget like 2 to 3 cars a month and will in the future not do it again and will be posting this email on Hello Peter.

I demand some sort of compensation for missing my flight and for deleberly giving me broken cars once can be a mistake but twice definitely wrong.
