need a call back from a realtor

[Sam Leon]

very interested in a SS property in Miami.

Called the agent, left voice mail, no reply.

Called his office, his assistant said I have to call or email him. So I emailed him as well.

He is the agent and also the broker. So there is no one else to go to.

That was a week ago.

I left another message two days ago. Nothing.

His office said he is around, but busy with meetings, clients.

I asked if someone else can show me said property, they said I will have to call him because "he play his cards very close to his chest"...okay, I am not playing anything, I am looking for him to return a simple phone call.

Now get this, during this week of me trying to get a hold of him, the price of the property dropped twice.

Twice, and not returning calls.

Think he has a buyer lined up and this is just to get the prices gravitating to his buyers pre-agreed upon number while telling the bank there have been no interest?

Thoughts on what I could do, engage a buyer agent to make the call? Will they be more responsive to an agent?
