ha.... The customer service at the Beşiktaş shop is extremely disappointing.

I purchased the product because it was advertised on the website as including the sponsor logo. However, the item I received does not have the sponsor logo. I have contacted the seller multiple times about this issue, but they keep ignoring my inquiries. What should I do in this situation?
