UPDATE:
I just got my 2 transfers cancelled and this is what MG told me:
Walter S: Yes, I can see in our system that your transactions have been successfully cancelled. Please keep in mind that the refund timeframe is within 10 business days. As I can see here, the transactions were cancelled because the receiver's financial institution didn't accept the funds. Since the receiver's financial institution didn't accept the money, MoneyGram needed to cancel the transfers because we can't keep your money. I do apologize for the inconvenience that this may have caused you, but you will get the money back, it's just a matter of time to have it back.
WTF
