BAD CUSTOMER SERVICE

I bought this car fro Hyundai in June this year however I am not happy with the service.<br> I booked my car in for service early November when it was 45000km on the dot and I was told its fully booked and I can only bring it in on the 25th Nov. When I sent it on Wednesday 25th Nov they said I need to pay as the mileage was over with1500 from 45000km. Which I didn't get it as no one have explained to me that policy. They gave me a quotation to pay R2533, that's ridiculous! My car is still under maintenance plan so why paying so much money?<br> I was give a call centre number *** to call which I ad no joy on, and I phoned Hyundai customer service where I was told t send an email to Angelee v on the 27 November 2015. I sent her an email and up to date nobody came back to me. I have owned other brands but never experience such pathetic service!!
