Dead Realtor

[Nat C.]

Sorry for the melodramatic title but what does one do when a listing agent appears to have dropped off the face of the planet?

In this situation, the offer has been submitted by email at 10K over list price.

5 days after initially emailing the listing agent, she still has not repsonded.

After calling her all day, every day, she still does not answer her phone.

When you call her office, they direct you to simply call her mobile.

Follow up emails to her with tracking on them, go unopened.

As I'm overseas and unable to physically wait in her office for her to turn up (assuming she's still alive), how would one go about contacting the agent and trying to buy the house?
