Time Share Nightmare

My stepfather purchased a time share property many years ago.  I think he and my mom used it a total of three times.

For years now he has been attempting to sell the time share.  Three years ago I went with him to meet with a representative who told my SF the property was now out of his name.  (After my SF gave him a check that day for $4,000.)   It never happened. 

Two and one-half years ago I took a phone call up at the house when he was not home.   It was another representative promising to sell the time share.  I informed him that my SF already paid someone a large amount of money to get rid of it.   The man then told me that THAT company was fradulant, and that criminal charges against them were in the works.  He said within a few weeks my SF would get his money back, which of course he never did.

Two evenings ago up at the house another man called stating if my SF gave him $2,994.00 (by the next morning) all of this would be over with.  I was furious, and my SF handed the phone to me.  It went back and forth for 45 minutes between the two of us.   He said the money they wanted now was for "legal fees" because they  had attorneys bringing charges against FOUR companies who have been involved with the scam.  He told my stepfather that he is "legally bound" to pay these legal fees. 

I have done some research on line, and I wouldn't give this last company one dollar if I had one million.  When I mentioned to the caller that we would send no money without consulting with my SF's attorney, he became angry.  He said "We have had your stepfather's banking information for a long time, Christine.  If we wanted to take money from him we would have done it a long time ago." 

Can anyone give me some advice?  We need to get out of this once and for all.  (The caller said he could arrange to have my SF's check picked up by FedEx yesterday morning.)   That was after I told him my SF does not have a major credit card, which he does not.  He said, that was actually in our favor.  He said if we put it on a card it would be well over $3,000, but my paying by personal check it would be $2,994.    That in itself is insane. 

I don't know if I am permitted to mention the company name on this board.  It was an office out of Deland, Florida. 

Thanks so much.  Sorry this was so long.  I am just fuming.
