N.W. Shell rip-off on gas price the sign out side it saying a price of $2.839 and the pump saids $3.359 Houston Texas

The Shell Gas Station has a sign out side with the price of V-power gas for $2.839 when i was putting gas i paid with my credit card and when i looked at the pump it was saying $3.359 so I immediatly stoped and went inside of the store to ask for my receip and when he showed me i ask him about the price of the gas and he said "sir your asking me after you had put gas already" so for me is a rip-off because i do not know to how many people he had done this many people pay cash inside but don't have a receipt and just put gas thinkig that the price of the gas is what they seen out in the sign many pumps don't have the price showing on the screen when your putting gas.
