MoneyGram Transfer of €5000 Claimed Without My Authorization

A friend sent me €5000 via MoneyGram from Germany. However, when I went to withdraw the money, I discovered it had already been claimed. The system shows the funds were withdrawn in Turkey at a specific shop, with the time also recorded, but I did not make this transaction.

I am extremely concerned and need guidance on how to resolve this issue. Has anyone else experienced a similar problem? I expect MoneyGram to investigate this matter thoroughly and provide a solution. This is a serious breach, and I demand immediate assistance to recover the funds that were unlawfully claimed. Please respond promptly with a clear action plan.
