Family Dollar

I'm a regular customer at this store & have never been treated with such disrespect. I know the store manager danielle & she would have not approved the negative behavior that the assist mgr showed me today. I went to purchase a shaver, that was listed for $10 (5 more on the shelf, same spot & price). Go to check out, it rang up $16. I paid for the purchase, but told the assist manager of the price it was listed under, I even went back to the isle & snapped a photo. I tried showing her the photo & she rudely stated that she couldn't see that. We walked back to the isle together & she saw all five pkgs under the $10 sign, in which at that point she should honor that $10 price. The asst mgr, then started to remove the items & ignored my request of honoring the $10 price. Stating that she "couldn't honor the price" because she didn't put the item there. So as a customer, that is no fault of my own & I then explained that the price listed should be honored. She refused agai with an attitude, so I asked her when danielle (store mgr) will be back in the store & i'll discuss the matter further with her. She then said "I don't know" loudly. I began walking out the store & I told her, "she was something else".. She then said, "don't catch a [censored]ing attitude with me!" which prompted me to walk back into the store, because I couldn't believe what I heard. I then told her, I will be calling corporate & I will speak to danielle (store manager) when she returns. The asst manager then threatens me saying, "I won't be speaking to danielle because i'm not allowed back into the store"..
I've been coming to this location for 4 years, up to 3 times a day & I have never experienced such negativity. Please view the video of the store (store #7492)
Photos are attached. Listed price should be honored & asst manager retrained on customer service.
