Suggest you leave a very clear message stating your timing goals and intentions to look at alternatives. Let her/him know you'd prefer working with her, but if she/he doesn't respond you will move on.
This will be complicated if you signed an exclusive buyer agreement, but if you did, then I suggest you contact the broker/manager right away. She/he should address your concerns and get your prompt assistance either from your current agent or an alternative.
Good luck, you are really down to the wire now, hope you make that deadline. Those darn short sales can really be frustrating and distractive.

Are you working with a Realtor? They should be able to help you find the right property. Or find a Realtor asap to help you.... it may not be too late on the property you mentioned but I wouldn't delay past today in seeing it and writing an offer if it is what you're looking for.
