jdrf review: falsely accused and violating my donors bills of right.

I had raised money for walk to cure, support and attended the hope gala, donated money . But despite of my support JDRF had falsely accused me of donating a stolen painting and had wrongfully banned me to attend any of there events, Mr Jeffrey Brewer had violated my donors bills of right and humiliated me by calling and informing a fellow donors about this false accusation, whom I know and had invited me to sit on there table for the gala.
I tried calling them and sent them emails but one called me back, I received a letter from JDRF telling that I had been banned to attend any functions and events and not to contact or call anyone from Jdrf. With the help of the gallery where the artwork came from and the artist I was able to established and proved that the painting was not stolen and the painting belongs to me, I had asked Jdrf to return the artwork and had asked them to write a letter of apology publicly and lift the banned.
Its been a more than a year no painting nor apology but I did get a letter asking me to donate and support there hope gala.
