Lying about job card service and bad customer care of Renault George

I had my 90000km service done at Renault George last year. When I had my next service on 105000km a while ago, I did it at another service station. The people there showed me that the pollen filter, that was on the job card shown as replaced at Renault George at 90000km service, was not replaced at all. It was an old, dirty filter, that no way could have been replaced only 15000km ago. I contacted George Renault, troubled, because, the pollen filter is only one little thing that was "supposed" to be replaced on the 90000km service. I mean, the timing belt was also showed as replaced.... If they did not do something as cheap as a pollen filter, did they really do the other things on the job card, like the timing belt??? I phoned, and spoke to a man that would speak to his manager, and would come back to me. He did not. I phoned again, and again, and eventually, the manager come back to me, said he will go into the case. I gave him more than a week to return to me, but he did not, I phoned again yesterday, the first man answered and said he will ask the manager to come back to me...needless to say, nobody did. I am really disappointed in there service and customer care of Renault George. They don't do what the say on there job cards, and don't come back to you if you have a problem. Even though Renault George is now under new ownership, I expect better service of the new owner and help. Even if its just to say, if there happen something in the next 90000km with the timing belt for instance, because according to them it was replaced on that job card, they will take full responsibility of it. Then I will know the new owner want to fix a problem. But unfortunately they just ignore the problem and hope I will go away. Will never ever recommend George Renault for doing your vehicle services.!!
