Fiat India — Extreme dissatisfaction with the service.

Hi Team, l am writing this to express my extreme dissatisfaction with the services rendered by fiat servicing center, ie., CIA industries pvt.ltd ., fiat division(Coimbatore) in hopes that you can help remedy the situation. On April 4, 2015 we took the car( fiat linea fire dynamic- AP29AH9905) to the service center as there was an issue with Engine heating., After diagnosing the problem, CIA team said that that they have to replace the Gasket ., for which they have taken whole 3 weeks of time., Later-on when we asked to deliver the car they have come up saying - there is another issue which they are unable to sort it out and are waiting for a help from pune ., according to the later diagnosis they have advised to change the complete Cylinder head which total estimation cost upto INR 50, 000 /-( complete on road ) . when we asked if the problem could be completely resolved by changing the cylinder head they said car would be completely fine after the replacements. After the cylinder head replacements is done ., CIA team failed to update the status, intentionally left our calls unanswered, they have postponed the delivery date at least 5 times saying that they have got some more replacements and adjustments to be done ., Finally they have sent a bill ofINR 80, 000/- and delivered the car on 4th June, 2015. when we took the car for the test drive., we found that the hot air blow which were working properly before the services aren't working then., the engine couldn't start when over heated and the coolant level was raising with engines acceleration., when we have reached CIA for the same, they said that its a very usual or common thing with cars, there is a slight leakage in engine oil and a problem with Piston rings. which are replace and charged INR 3, 000 for the same. If the total repair cost has went up to 83, 000/- we would have gone for the engine replace right?? we are very much dissatisfied with the CIA team as they failed to actually diagnose the problem, talk to the customer& explain the situation, update the status, give the details regarding expected service charges, expected date of delivery. If they have actually diagnosed the problem on time., and suggested the best option, the situation wouldn't be this worst. The car had the same issue with engine on 25th July, 2015.( this was the only reason for taking the car to CIA, Coimbatore)., If the car has still the issue unsolved why is that we have spent INR 83, 000 on the repairs and replacements.? If I couldn't see any change in the car what is that the team has worked for two whole months? Car was again taken to BUTTA Service center Hyderabad. after diagnosing they said there is a problem with piston rings and gaskat are not assembled properly and it takes 42, 000 INR to render the services again. am not ready to pay the any more bills. when it is proved that it is a mistake of CIA Team. I would like to take this complaint to the higher officials., I would not compromise with the reply from Mr. Amit, who was the point of contact during the services rendered and I am completely dissatisfied and fed up with his responses. He is not at all customer centric. I want any superior above Amit to address the issue ASAP. Thanks, Pradeep
