Tata Motors — extremely poor services

I have Tata nano reg. No. Gj 21 ah 4025. Had an accident on 24the July 2014. The car was dropped to dharmachakra motors at Canada(Gujarat) for repairs as they promised for good job. Till day the car is not repaired. Extremely poor service..false commitments..000 effort for customer support...rattan Tata's dream into vein... Can u imagine a car not being repaired for almost 10 months.. the matter was duly discussed with amit & Duran of Tata motors.. they also stopped replying to mails. I can give u all mails conversations if reqd. Looking for the matter to b ressolved and strict action against the dealer. And off course remuneration for me from the dealer as he has taken money from me in advance for repairs.
