Bad customer service

I am currently receiving the most ridiculous service from Edgars. There is a black boot advertised on the Edgars website that I want to buy. However, I cannot find the boot in any of the stores. I can only find it in brown. I asked the sales assistant at the Sandton branch to source the black one and he never got back to me. So I emailed Edgars customer service and sent them the picture on their website and was told that they can’t help me without a SKU number. They told me to go into a store and get the SKU number, which I did. The response I got when I sent the SKU was: Please be advised the below SKU number is for the brown shoe. What?! Of course it is! What part of I can’t find the black shoe is confusing? Dealing with Edgars is like banging my head against a brick wall.
