Size veration and not cancelling my order and not refounding

I had ordered Puma X-Ray shoes in size 9, which was delivered to me on 13.10.26. The size 9 shoes were too small for me, so on the same day, 13.10.26, I requested a return and exchange for size 10. This exchange request was confirmed by Puma at that time. However, on 14.10.26, I found that both orders, the original size 9 and the exchange request for size 10, were shown as cancelled. I am still left with the size 9 shoes, which do not fit me and which I do
