I think you need to do some more reading on how the resolution center works. Initially it is common practice to ask for an extension during which time you are free to try and work out a resolution with the vendor, if you want a reship then make a proposal for a reship, if the vendor declines your proposal then you are free to request a refund instead. The resolution admins will only become involved if you are unable to reach an agreement with the vendor, if that happens they will adjudicate on your case and make a determination, all SR resolution decisions are final. Obviously they cannot make the vendor reship to you but they can give a refund if it is considered appropriate. There is also the chance that none of your proposals are upheld though and the vendor is awarded 100% and you get nothing, it all depends on the merits of your case.
