Western Union Still Charged me $15 dollars(sending money in minutes) but my family got the money after 4 days! Internet

I sent money to my brother in the Philippines on September 30th and I paid $15.00 so they can get the money in minutes. They sent me through email a confirmation of the transaction. My brother sent me a text message indicating that they could not get the money. I forwarded the email that I got from Western Union and told them that the company deducted money from my account so everything should be okay. By October 2nd, I got another text message from my brother and he said that they still refuse to release the fund and wanted me to verify the transaction. I called Western Union but they kept transferring me to several people. I finally was able to talk to a supervisor but instead of resolving the issue, she claimed that Western Union called me numerous times yet, I do not have any record of them calling about my transaction. She said that Western Union has the right to place transactions on hold if it was suspicious. I have been sending money through their company for years, and this is the very first time that I got a comment from this company. I have great track record and their assumptions were ill-wrong. I asked the company to refund me at least $7.00 of the transaction fee since they did not deliver their part of the commitment, which is delivering the money within minutes. The supervisor refuse to listen to my explanation and all she said was do what I have to do, which was nothing. She did not even acknowledge that it is their fault for not letting me know that the money needs verification, or was put on hold and all she said was that I should have called them sooner. She also claimed that the company doesn't send communications through email since they do not know who will get it, yet they sent me a confirmation letter, indicating that the transaction went through. I think it just fair to get a refund from the transaction fee since the money was sent three days later instead of minutes.
