American Financial Services/Solutions Time Share Sale: possible scam. Unable to contact above named company. wilmington, Delaware

In March we were contacted by Leslie Allen of American Financial Services/ solutions located in Wilmington DE.  She informed us that there was an interested buyer  in Texas regarding our time share in Kissiminee, Fl.  The offer was for $23,500.  If the buyer was approved ,  we would need to send a fee to assist with closing costs.  In response to our question re: paying closing costs, Ms Allen explained the need to cover title search and paper work. 

We did research the company in Delaware and found  it to be legit, but still unable to reach AFS by telephone.

Approximately a week later ,  Ms Allen telephoned again staing that the buyers were approved and that we needed to complete forms which were e-mailed to my wife and myself.  she would review those forms with us via telephone.  

Forms were to be completed and Fed EX to:  AFS/Solutions/ Processing; 2423 south Orange Ave.; suite 138;  Orlando, FL  32806.  Also sent was a cashier's check for $2295.00.
