Realty Brokers International Title and Insurance Fund Ripoff for Palace Resort Timeshare weeks Shawnee Kansas

I received an email offer with an official looking "Letter of Intent" with an offer that they would rent 10 weeks of my Palace Resort timeshare.  Told me I had to send the Palace premier rate for the 10 weeks, which amounted to over $5500, which I sent via international wire transfer.

Two days later, the sent an email indicating that I needed to send an additional  $4300 which they claimed was required by the Mexican Government.  When I demanded that the transaction be canceled, they told me that there would be a cancellation fee of $3500.  When I agreed to the cancellation fee which I assumed would be deducted from the money I had already sent, they told me I needed to wire the $3500 to them before they could refund the full amount I had wired to them back to me.  

they have a pretty good operation going with authentic appearing documents. Each person I spoke with was aware of the supposed transactions. However, as long as I appeared interested, I received emails and telephone responses within 24 hours. Once I decided to cancel the transaction, suddenly no one was responding to my emails and When I called, I was told that the person I'd been dealing with was on holiday and probably would not be returning to the company. When I asked for another person I'd been receiving emails from, I was told that there was no one in the company by that name
