Miniso Ships Wrong BT21 Pencil Case on Trendyol After Confirming Character Request

I purchased a BT21-licensed 21 cm large zippered pencil case from Miniso's Trendyol store. Even though there are a total of 7 different character options for this product, I explicitly stated twice before placing my order that I specifically wanted the Chimmy character. I received a positive response confirming that my request was forwarded to the warehouse and that Chimmy would be shipped.

When the item arrived on August 11, I saw that the Mang character was sent instead of the Chimmy I had requested. When I messaged the store regarding this, they claimed they did not have Chimmy in stock. I then clearly asked which characters they actually had in stock at their warehouse, but despite asking twice, I was only told to "contact Trendyol." They provided no clear information about their inventory. While trying to find out which characters were available and which were sold out, being constantly deflected to Trendyol made me feel ignored and did nothing to resolve my grievance.

My order number is 11491711033. I refuse to accept receiving a different character and then being denied transparent stock information, especially after I explicitly requested the Chimmy character from the start and received confirmation. If the Chimmy character I requested is in stock, I demand that it be sent to me; if it is out of stock, I want a clear and transparent list of which characters are available, along with a satisfactory explanation regarding this entire process. If Chimmy can never be shipped or if I have no option to choose another character, I do not want to be pushed into a return process without first receiving a clear and direct explanation.
