Failure to refund moneyorder even after bank paid them..

I filed a replacement request in January 2022 to replace a $400 Money Order that was stolen and fraudulently cashed. It is now October 2022 - the bank paid them back the $400 and still I can't get them to return the $400 to me. Additionally they charged me $35.00 to "investigate" the fraud. I've called the 800 # about 50 times - never can you actually talk to anyone. There's just a circular phone routing tree that ends with "goodbye". What a scam this whole thing was - I will never use MoneyGram Money Order to do anything except wipe my ass.
