Dollar Tree

I drive an hour to this store to get a certain product. I come so often and buy this item in cases that an employee there who said she did the ordering told me just 4 days ago that she would order me cases of this product and would hold it for me. Today, I asked an employee stocking if any more of this product was in the back, she said I can not check for you anymore. I said the other lady said she would order this product for me. I even said the ladies name. She ignores me and walks away. I proceed to checkout and I asked the cashier when would this lady be at work because she told me she would order a product for me and told me she would keep it in the back for me. The cashier said she is off the next couple of days. I can not help you. Is customer service so bad you can not take a minute out of your time to look for a product that was ordered for a customer? I work in retail myself and if I ever acted the way these ladies did to me today I would be fired on the spot. I'm so aggravated with this issue. I even drove another 20 miles out of my way to go to another dollar tree branch in search of this product with no luck.
