Dear Sir, This is reg. my Skoda Fabia 1.2 TDi which was suddenly started noise in engine while driving from my home to office in the Morning at around 10:30AM. I called tool free number(18001026464) road assistance on 27/06/2012 at 10.30AM. As per the advice I drove the Vehicle to nearest service center at Mahaveer Auto Private Ltd., Somajiguda, Hyderabad. I was purchased the car on 30/05/2011 from skoda dealer Mahaveer Auto Private Ltd. Hyderabad only. From the past 9 days I was told by the service engineer that there are working on it find the cause. I have approached Mr. Farooq, Customer Relation Manager from Mahaveer and Narayan Sheshadri, Customer Relation Manager, Skoda Auto India Pvt. Ltd, Nothing being progressed since 9 days the response also very poor. I am spending daily INR 900 to travel to my office which is 35kms away from my home. I was requested to provide alternate car till get rectify the problem. On Monday they arranged Taxi car(Yellow Plate) for self drive. I have rejected that car since I am not a professional driver to drive the TAXI plate Vehicle. In this reg. need your advice and process to approach consumer forum to address my concern to justify and come out from this situation. Please advice.
