Return item issue

I am very disappointed, you know my friends always say that I love buying online, and I really do and I think I had forgotten why I do. But today I was reminded why I prefer to buy online, rather than going instore, firstly TFG/Bash, please, I please with you, after some time, or atleast after every 6 months offer some sort of training to your employees, their customer service is trash, I'm sorry I don't have another word for it. It's as if like they are forced to be there, I am currently in other town, due to work, but the service is still the same as your employees from my own town. At first I had thought maybe I expect good customer service because we're I work I offer great customer service to clients, but no, that is not it. They are not even trying. I ordered clothes and shoes online, I went to fetch the packages. I was given my packages, though it seemed as if like the lady was a bit lost, fine, there is nothing I can do, after receiving the packages, I checked if the shoes fit, and one pair didn't fit me, it was small. I was at Totalsports and they told me I cannot return the shoe to them, because they do not sell that label there, I was told I must go to Markham's, they will be able to assist me there, because they sell the shoe. The lady that assisted me became a bit troubled when I explained that I was sent by someone who works at Totalsports, yes given, she was not irritated with me, just she explained that the other store, which is Totalsports did that with another client too, and they were not able to assist the client with the return. Ohk fine, they further checked on the system if they will be able to lodge a return, and they told me that they can't, their system doesnt allow and explained again that they do not sell labels in their store. Ohk cool fine, I left, arrived home, checked the Bash/TFG website as to how can I log a return, went to the help button, put in on the necessary items, and clicked on the item I wanted to return, only for the robot/system to respond saying the item is not returnable, I checked the return policy, and nowhere does it talk about G-Star RAW shoes or sneaker been unreturnable. Second reason why I prefer buying online, for the convenience, I loved the show, saw it on the bash website, there is no G-Star Raw shop where I am currently based, I received the shoe, unfortunately it is small. I don't know now, I need to return it, I am unable to return it, the policy says you can return an item within 30 days, where I am residing there is no G-Star RAW shop, in fact, I have never seen it with my own eyes. If I can't return the shoe where I received it, and can't return it via courier, where should I return it Bash/TFG. You are ruining the fun, the convenience in what buying online is, the true definition of buying online. I need assistance in regards to this please, the last time I complained, I was blue ticked, I swore to myself never to buy only with you guys again, now I have forgotten about that horrible experience, and now I am getting triggered again. There is nothing I can do with the shoes, they are small for my feet, I need to return, and I won't be able to go to a G-Star RAW shop, one nearest to me is very very very much far from were I am currently staying. Please assist.
