Mahindra And Mahindra — Warranty promised , payment taken and then failed to supply, cheating done with me by deccan sales, bhopal

Address:

I have given engine of my Mahindra Grader G75 chasis number MDZGA6BGEH6L49728, engine number NH65WDE0123 for repairing at deccan sales bhopal. They have promised me 3 months warranty, they have not done their work properly as after repairing engine doesnt work even for 25 hours/ 5 days and when contacted they want charges again, which is very poor commitment from such a reputed company like mahindra, please help
