It sound like you may have a relationship with an agent working on your behalf and you really need to get with them for answers to your questions. It would be highly unethical for another licensed agent to become involved when you have a relationship in place as we are bound by a Code of Ethics.
Your best bet is to sit down with your agent and go though everything in detail and make the appropriate decisions.
Best of Luck,

Perhaps your best advocate would be a combination between both your buyer's agent and the listing agent. An "I don't care attitude" of this nature could end up as a foreclosure...........a united front consisting of both agents may get them to see the light.....
