I don't think they will reverse this for you. They once did it for me but that was due to their error. I had my BA number on the boarding pass but somehow this was credited to MPC. I first called BA who told me to call MPC to see if they would reverse the credit. MPC asked for images of the boarding passes and said that they would reverse this as an exception to normal policy given the evidence provided. They made it quite clear that this was exceptional but that was also MPC. If you just credited it to Asia Miles, and not MPC, then you could try to contact Asia Miles but I wouldn't have high hopes.
