Dollar General review: A very rude employee and unethical behaviour

I visit The Dollar General Store #06905, to look for Disinfectant Items, didn't find nothing of those items. I bought a 12 Pk of Michelob Ultra beer, because I saw the sign that it was on sale for $14.00. When the cashier scan it, it came up as $14.95, I told her that the sign said $14.00, she said she could not change it, because the register didn't let her. I told her if she was going to give me something else for the difference, and very rudely she said no. I told her go, and check the sign were it says the 12 pk is for $14.00. She was very rude, and told me she couldn't, because their was a line of people. I told asked her for her name, she grabbed my receipt, and wrote her name on it, she wrote, Yadira Olivare, I asked her, and the name of her manager, or general manager, she just ignored me, and didn't wanted to give it to me, I asked her several times, but she continue to ignore me, and told the customer in back of me to come forward, and she just left me talking like if I was stupid. I felt very embarrassed by her actions, I just left, and I even forgot my debt card. She was very rude, and not friendly at all. I need for the general manager of this store #06905 to make contact with me at [protected]@yahoo.com.
