Store not carrying stock frustration

It's very frustrating that the only miladys branch in the upper highway doesn't carry stock in the bigger sizes. Apparently this is because they don't sell, and as far as I know this has been the case since last year at least. Well the last two times I've been in there there has been at least one other person looking for the same size as me. The staff tell you order online. But what about trying on? With all the different styles (I'm particularly looking for pants) I have no idea what the fit is like. Yes, you can return, but what a hassle, you then have to start from the beginning again. Alternatively they will order for you. Two weeks delay. Then you can go back to try on. If you don't like them you start again. I wonder how miladys can advertise their big sizes and not stock their stores with said sizes. One other issue is that a lot of their online stock does not go up to 50 as advertised. Much of it stops at 46 (I'm 48), a lot of it even smaller. I've written to miladys about the issue but never received a response. Is it really too much to ask to be able to walk into a store that advertises certain stock but doesn't even carry it. I've been shopping there for decades but find myself looking more and more for alternatives.
