Fiat. . Palio 11slx — Bad service in Patna

1. I purchased a Palio with the full assurance that the Tata-Palio dealer in Patna- Guinea Motors will take excellent care about service and warranty matters.The Tata dealer which deals with Palio as the authorised service station has proved to be absolutely otherwise. I had an insurance claim and got it repaired in December 2007 from Guinea Motors. So far the Insurance company, Reliance has not made any payments to me. I learnt with great difficulty over 8 months'' frustrating efforts that Reliance had already paid the money to the dealer Guinea Motors who collected money TWICE from me and the Insurance company. Guinea Motors now refuses to refund the money and some people working in the office of Guinea Motors when attempting to contact them in person or on phone, either slam the phone or invoke mother and sister foul language! The Tata Motors representative in Patna is also in league with them and does nothing in the matter. This kind of behaviour cannot be expected from a reputed company which bears the name of Tata. It is a shame that Tata Motors has such representatives and dealers from the underworld.
2. Second service (6 months) for my car was due in April 2008. I went to Guinea Motors who said that they did not have the oil filter in stock so I should come later. I said that I was going abroad for many months to which they said that they would wait for me. When I sent the car for servicing in September, they said that now I would have to pay for the service. They did not change the oil filter either saying it is not available in India but charged me for the filter. And they supposedly put a Bardahl additive in the oil for Rs.500 without my permission and the car within 4 days started giving major problems and stalled many times. Probably they did not change the oil either, although they charged me for that. Then I had to get the oil changed again. This again cost me a huge sum of money. This is preposterous and cheating by a Tata Motors.
3. My car is due for annual service in October. Where should I go and where should I get it done as it is necessary for the Warranty and Extended warranty that I had paid for? The Tata representative in Patna says that he has no solution to offer.
