Silverleaf Resorts, Inc don't go if someone says you have won a cruize N RICHLAND HILLS Texas

They called me saying that i won a cruize - they gave false sales pitch and made me buy the property . they dint tell me that i have to pay maintainance fee for lifetime . i stopped paying for 3 months cause i coundt afford it i was a student then .  they reported to the credit buraue . My credit score went down by 100 points. They kept on calling thousands of times . one day when i answered they told me that they will do foreclosure an it will blow my credit score so i decided to pay again . i can still see as late payment in my credit profile and its still showing as inactive . i tried calling them manytimes they will tranfer the call from one person to another and they hung up after half an hour. i am fed up with this and i  need somene to help me and clear it my credit file .
