Business ProfileforCircle K

I went in to circle k a few months ago the person working I don't know her name but she is the only one that has piercings in her dimples on her face I asked to purchase 2 scratcher tickets I said any 5$ ones a d she put 2 on the counter upside down which I thought nothing if at the time she then took my money but didn't open the register I got to work and I saw they had already been scratched just the bar codes and scanned to see if they were winners which they were not so I did end up getting them replaced with ones that the employee had not stolen scratched and put back, then I went in a month ago same girl and she tried to rip me off for 18$ of gas I told her 20$ of gas and I paid with a 20$ and again never saw her open the register but I went to pump it and it only went to 2$ so I went in and said the pump stopped at 2$ she looked at me & said "u said 2$ of gas and gave me 2 one dollar bills " and shocked I said " no I gave u a 20 & asked for 20$ in gas" the only thing that saved me was another employee had saw & heard so I was given the 20$ in gas I paid for. Today I went in and asked for a pack of camel MENTHOL CRUSH cigarettes I was given regular camels when I said something she smirked & said nope u asked for regular that's what u get, I would never ask for regular I don't smoke regular so I again got screwed out of my money, upon leaving she called me a stupid white bitch, mind u I have never met this girl she has tried to rip me off every chance she could I can only assume it's a race thing as she has no racially assulted me and I no longer feel safe to go in to my neighborhood convenience store I don't know what I hope can be done I just need people to know what kind of person is working there and it's not right I am verbally assulted and stolen from when I have never done anything wrong except be the race I am that doesn't give people the right to steal from me and to verbally assult me I'm sickened by this totally sickened
