Hindustan Petroleum Corporation [HPCL] — Service quality at your outlet-moodbidri karnataka 574227

Sir,
Last month when i went to your filling station at moodbidri in karnataka for petroel filling for my new maruthi petrol car staff filled diesel into the cars tank despite petrol being written in bold letters on the tanks lid. When confronted the staff for this negligent act they were very abusive and i had to incure rs 3000 at local maruthi auto dealer for draining the tank, toeing car to their garage etc. I request you to takeup this gross negligence with your dealer
