Steven Amore Kicker Wyndham Green bay Wisconsin

I purchased a time shares points from Wyndham resort in Wisconsin dells at glacier canyon 5 yrs ago. At the time they told me I would not have any problem getting a rservation at any time at glacier canyon which is owned byWyndham well like every thing else they told  was a lie.They also said I would have no problem selling my points, I can't give them away no body wants them, on top of that I receive these phone calls about crooks wanting me to pay them to take my points of my hands, what can I do ?
