HYUNDAI HEAD OFFICE AND BEDFORDVIEW DISGUSTING SERVICE, TAMPERING ON CAR SERVICE, RIDICULOUS QUOTES AND TAKING ADVANTAGE OF FEMALE DRIVERS!!

I took my car into the Bedfordview branch a week ago for a routine service and told them about a slight shudder on the car on uphill which happened once or twice randomly and check what it could be. They came back to me with a quote of over R7700 for an O2 sensor to be replaced. For the last 4 years, my services with Hyundai had been a total nightmare....first they told me a bolt had a crack in it and they could not explain it, then the Sandton branch added antifreeze to dirty water and I had to pay to flush the radiator. They also double charged me for antifreeze. They blamed me in the end saying I added ordinary water which I would never do, then the following year they quoted me for a shaft seal a couple thousand and this year I found out that seal was leaking again but they say it was not poor workmanship, it was a faulty part, even though brand new, which does happen, then this year I have to change the O2 sensor!?! I rejected the ridiculous quote and after driving the car after the service it started smoking from the exhaust and switching off on the road and the brakes could not work properly. I did not take this car to them in this condition! It seems they tampered with the car to force me to replace the sensor and take their ridiculous quote. They obviously take advantage of female drivers thinking we will fall for their tactics. There is a definite pattern here. I tried to contact the principle dealer and he ignored my emails and 5 phone calls until I started contacting head office which finally got his attention. I found that Hyundai head office has NO EMAIL for complaints and they don't answer their phone and leave it to ring. So how do we get to report our complaints? When I contacted a senior guy at head office about the antifreeze issue 2 years ago he told me there is no proof of what I'm saying and he closed the case!! I did send them all the proof of the invoice, my service docs and photos of the dirty water in the car. That's how pathetic they have become! Hyundai has seriously lost all sense of customer service in the last 4 years. The lady assisting me for my service also forgot to give me my service book back and later I discovered that she didn't fill it out under the correct kms on the book. She had the nerve to call me and ask for a rating for her service and **** about her name when she called me but I recognised her voice. The principle dealer til today has not responded to all my emails even though I asked for a response 5 times now of everything he reported to me but he won't put anything in writing. Every email I ever sent him years ago he has refused to respond in writing! He only contacted me 3 days after my report that something was wrong with the car. He then rechecked the car denying all my complaints I reported on it and is insisting its the O2 sensor and he says its a complete coincidence that the car is in worse condition after the service! He won't admit they did something wrong on the service. I asked him further questions and told him to put all his findings and his answers in an email which I still don't have today. Despite me filling out the form on their website of my complaints twice I have not heard anything from head office and its been a week! My car is not operational for over a week! They offered me a discount but it is still double what other companies charge to repair! Hyundai quote is 4 times the normal price to repair. As for Hyundai head office, that's how little they care about their customers of 12 years! Disgusting!
