The New York State Attorney General’s office has launched an investigation into NYCharities.org an online fundraising platform that has failed to distribute hundreds of thousands of dollar to New York charities over the past several months.

The investigation, being conducted by the Attorney General’s Charities Bureau, is based on more than 100 complaints from individuals and organizations. The claims of unpaid contributions range from $200 to over $100,000.

Charities that wish to submit a complaint can do so on the Attorney General’s website, via an email to charities.complaints@ag.ny.gov, or by calling the designated hotline at 1(800) 771-7755.
