The worst service I have ever received!

It was by far the worst attitude I have ever received from an employee! I went to look for specific sneakers and they didn't have it in my size (which is understandable) but when I asked them to look at their other branches the lady rolled her eyes and started talking to her collage about it,like it was not part of her job description to make it worse when I asked for her name she refused to give it to me and when she finally did what I had asked her to and said she'll only find out about it on monday because she doesn't have time at that moment. I have never been so ill treated and so disrespected in my life! And she still has not gotten back to me about it. It'll be much appreciated if you will look into this issue. Kind regards Alison
