Transfer of point should be pretty speedy I would assume. Get an owner that will transfer and pay them via paypal and the points should hit your account very quickly..........
You can not call and make any changes or speak to MS about that reservation since it is under another member's account even though it is in your name. The owner of those points would have to be the one to call MS and add ME info, add/remove DDP, make any changes to the reservation, etc.
