Ref: dealer code 125059 (Recalling from memory, need to confirm) petrol pump at puthiyakavu, mavelikara, alapuzha dist, kerala

Above still was found charging xp rate for normal petrol delivery nozzle. While asking on it (26 june), they have written "xp" by hand, using sketch pen at same nozzle and taken xp cost from me. It is not clear whether they gave me original xp or cheating me by supplying normal petrol.
Again i visited the same station on today and found the same scenario that same nozzle charging xp cost (75) and found no xp writing on it. It raised a lot of doubts on me and suspecting they are cheating customers.
We never expect such type unprofessional act from iocl outlet.
