Petronas review: not honest on amount of petrol

My car was a Myvi. Last week (13/8/2019), i filling petrol at Petronas Taman Bersatu Rawang, I paid RM50 but 3 column that fill.Today(26/3/19) i went to Petronas Rawang Industrial Park 1, i paid RM63.39 with 7 column full. This is have a big problem on the amount of petrol! I strongly suspect that Petronas Taman Bersatu Rawang have cheated on the amount of petrol. Hope your company do a checking on the Petrol station. Thank you.
