Pull And Bear Item Cancelation Problem

A few days ago, Pull and Bear unexpectedly canceled one of the items from my recent order without any prior notification. I didn't receive any emails or messages about it. When I placed the order, everything was in stock and the rest of my order was not affected. Interestingly, I faced some challenges when trying to add sizes to my cart for other items, but surprisingly, there were no problems with the canceled one. As a customer, this has caused a lot of inconvenience, and I firmly believe the product should have been sourced from the store's inventory and delivered as promised.
