Western Union Transfer Used For Fraud - Recipient Disappeared

I am writing regarding a Western Union money transfer that resulted in fraud and financial loss. On 25 February, my fiancée sent 7,500 SEK from Sweden via Western Union as part of a business deal. The money was to be received in Indonesia by a person who has now defrauded her. Western Union has confirmed that the money was received in Indonesia by the intended recipient. Immediately after receiving the funds, this person stopped answering calls and then blocked my fiancée on WhatsApp and Telegram, clearly indicating fraudulent intent and abuse of trust in this business arrangement. My fiancée has already filed an official report with the authorities about this incident. In light of these circumstances, I request that Western Union urgently investigate this transaction, fully cooperate with the relevant authorities, and provide all necessary information to help identify and prosecute the recipient in Indonesia. I also request a refund of the 7,500 SEK that was sent, as the transfer has directly enabled a criminal fraud. I expect a clear written response explaining what steps Western Union will take to support the investigation and what can be done regarding compensation.
