Indian Oil Corporation [IOC] — display and supply cable bent condition

To day at 14:00 hrs i am md. Yakub pasha vehicle no ap 36 au 3129 went to ioc bunk at beside st. Thomas school, rec road hanamkonda. There is no display board about normal petrol and extra petrol i was in line at the time of filling i asked for normal petrol the person who filling the petrol said go that side at that time there were three vehicles. I have gone another side and filled 3 liters normal petrol. At that time i have observed the normal petrol supply cable is bent condition. After that i have taken a bill for 3 liters vied cash bill no 10938 and i went to the supervisor room and asked about complaint book but supervisor/respondent not available and the worker asked about the complaint, i have refused to convey the matter with him. I again asked complaint book they were not provided the complaint book. Due to this reason i am approaching this online complaint. They are cheating the public with out intimating they are selling extra petrol.
