Fiat India — fiat punto fake servicing

Address: B - 42 A Nirala Nagar, Lucknow, Uttar Pradesh, 226020

We sent our car, punto, for full servicing and they gave us a receipt as well, but despite that the car is not running smoothly. It shows messages like "check filter" and upon inspection it showed no signs of servicing, oil was not changed, nothing was done even though we were charged for it. We have paid a huge amount but have not got any results. Please look into the matter of these fake services.
