Shopping at Kohls

Last night I went to Kohls after work and I got the best leather gloves, a wonderful jogging set which I will use a lounge wear, and some slippers cuz I lost one of mine. So I got 15% off the sale price and I got a $10 dollar coupon off my next purchase. I think I'm going back tomorrow, they are open until midnight. Earlier this week I got gas a a gas station in Parkesburg and I paid at the pump and when I was done the pump said "please see attendant" so I went inside and told the attendant that I paid at the pump and it didn't give me a receipt and is that why I need to see the attendant? and he said which pump and how much and he rang it up again and I asked several times if I would be double charged and he said no. Well I was double charged so I have to go back tomorrow and tell them that I got charged twice, hopefully I get my money back and I won't be getting my gas there ever again.
