Hilton Grand Vacations Took money, never delivered materials, want more money to avoid forfeiting my original payment Orlando Florida

In July 2016, I was transferred to Hilton Grand Vacations (HGV) after booking a room at a Hilton property.  I paid approx. $300 for a 3 night stay in Washington DC.  I didn't confirm dates as I wanted to surprise my wife.  They promised to mail and email more information.  Nothing arrived.

I tried calling and leaving voicemails, no response.  After several months I gave up.

In December 2017, I was told that I received a call telling me I needed to pay $100 right away or I would forfeit my money (the one for the stay them promised but never delivered).  I finally got an email wishing me a "Grand Day".

In January 2017, I received the same call.  I got a number to call, but it leads to a voicemail system that I must know the extension.  There is no option for a directory, and if you hit 0, your call is disconnected.

After over an hour, I managed to track someone down who could help.  It seems I can't book a vacation now because my record is locked.  Two voicemails and an email later, still nothing.

Either they are legitimate and ridiculously incompetent, or I've wasted my time on a fraud.
