Speedway review: cashier called me a liar and wouldn't give me the $5 she owed

I visited the speedway location on w main st in batavia ny today 2.1.20 at approx 6pm. I bought a back of marlboro cigarettes which came to $11.16...I handed the cashier 3 bills (2 - $10's and 1 - $5 bill) totally $25 and told her to put the remainder in gas on pump #3. I proceeded to pump gas and almost pulled away until i realized that she told me the gas would be $8.84...Which is wrong...It should have been $13.84...$5 difference. I went back inside and asked how much the cigarettes were and why my gas amount was only $8 and change when i gave her $25. The cashier told me i only gave her $20...But i told her she was wrong and i gave her $25...3 bills which were 2 - $10's and a $5...And she proceeded to say i was lying. I told her there is a difference of $5 owed and to just put it on pump 3 so i could put the gas in the vehicle. I went outside and was telling my husband what happened and the cashier came out to pump 1 and was telling me never to come back to the store and then proceeded to not put the gas on my pump. I told her she can't tell me not to come back and she told me to call her manager. We were in a hurry and just left because my husband said we can call the store and file a complaint. So this is my complaint. I was called a liar by the cashier and then she embarrassed me in front of everyone! i visit this store every single day and spend a lot of money there! i want a refund, an apology from the cashier and for her to lose her job! my name is tara hall-dilaura and my speedway card number (taken from the key chain bar code) is [protected] 1 so you can see that i was there around 6pm and used the card and then the cameras can be checked to prove that she is wrong and she disrespected a loyal customer for no reason and called me a liar...As well as trying to ban me from the store! i hate to do this...It's not in my nature but she is a terrible employee!
