Indian Oil Corporation [IOC] — negligence ioc petrol pump

Address:

Chandigarh, Punjab, 140307

This is in refernce with the complaint i made with IOC on 16-November ref number -SR No- 1-[protected]. I want to bring to the notice of consumer forum that I got my crefilled with petrol on 16 Nov 2018, but the IOC refuel person did not close my car oil tank cover. and as i was travelling i went to Gurdaspur from chandigarh withour realizing that the oil tank is open.
when i came to know about it i made an online email compaint to the IOC Department and requested them to compensate me the amount needed for getting my oil tank checked for any dust particals or any other particles as it was open due to the IOC people fault.
They made the enquiry by checking CCTV Camera and agreed that it was their fault. But still they are not compansating me for the same. In case if some technical issue comes in my car who is responsible for that.
this is not acceptable to me. i need an answer from IOC.
IOC Itself commited their fault
