Sunoco Gas Station Pump will not turn off. Columbus Ohio

I believe the Sunoco gas station at 1555 Polaris Parkway in Lewis Center Ohio needs to be investigated. On multiple occasions, purchasing gas at that gas station, the pump will not turn off. You try to pull the handle out of your car gas tank and it won't release and stop the gas flow. you really have to play with it. You end up buying more gas than you want. Have experienced this a couple times . So my question to you is this,... when you buy one gallon of gas are you getting a full gallon?  Maybe that gas station needs to be checked out by the state of Ohio and its Regulatory Commission to see if it's cheating people in another respect. Also, could it have credit card scimmers in the pumps? Also, My son who smokes, tells me he pain a dollar more for a pack of cigarettes than at any outherstore in that area. I believe the manager of this store is not on the level.
