We have already given for service in mgf hyundai padivattam for engine missing case and they took arround 3 weeks to return after charging a huge amount for service. They asked to change many things and we did it. But the complaint still stays. Then why the hell they took this much time and money from me. Are they bafoons to say they are mechanics. I want the complaint to be serviced and i wont give a single penni again or else i will go to social medias and news and screw you. Now me and my family is bloody scared of driving your fraude companies vehicles.
I need to get my vehicle ready by next week or else return my bill amount. Rest i will take care. I am 64 year old senior citizen and i will give case against you for fraudlent.
