Hindustan Petroleum Corporation [HPCL] — payment issue with hpcl vendor

I have done work at one petrol pump ku petrol pump (Near bharuch) under contract of kanishka construction owner name mitesh bhatt and place ahmedabad. Now this party is not given of amount which i have work at site. I have many complaint zonal office vadodara region hpcl but they didn't have any support. Just because of this kanishka construction is strong connection with hpcl officer so that they didn't support me. I have given written mail and application but they didn't given any feedback and they didn't take any action against this vendor. I have small vendor but i have hard work. My complaint didn't recognize because i am small person.
Arvind govil rgm (Now transfer), mr. Karuna, mr rahul palani,, mr rushikesh pawar, i have told my all matter this persons by meet, many calls but they didn't take any action. This vendor fraud gstn bill of cement and other material and steal gst tax. If hpcl take any action against i am sure this vendor make many fake bill in cement and other item. And also they are doing many thing at site which is wrong but no one take any action. And its require one audit which work done by kanishka construction, i am against this corruption. If my this application is not consider i will sent one draft to pmo soon against this vendor how they steal gst in government company but no one take action against this vendor. As per my opinion this vendor is black list from hpcl and how people support corruption and not support small vendor by officer and also make fake gst bill. I am awaiting your feedback.
