Inconsiderate staff

I was so dissapointed with Peo Evaton mall,my daughter went there to buy something,she was carrying an insulated mug and she forgot it,after 5 minutes she came back to look for it as there were no customers only staff,they told her that they ddnt see anything and they even refuse to look at the cameras,what bothers me the mosh is that,that mug was too sentimental to her because her late father bought it to him before he died last month,they ddnt even show any remorse
