New iPhone 13 and tax free

I bought a new iPhone 13 and Apple Watch in Amsterdam on February 16, 2023 at Media Markt.

When I was buying, I asked tax free form. They scanned my passport and gave me attached documents.

At the Rotterdam airport, I got stamped my tax free forms and they told me I have to send my documents to Global Blue . However, they did not give me further information. After I arrived Turkey, they said they do not know about tax free.

My question is that how I can refund my tax. Here are the proofs of my documents .If you help me about this issue I will really appreciated. Sincerely yours
