Omaze is a US Federal and California state registered "for profit" company. It is not a registered as a charity.
Yet they claim donations to them are charitable deductions and claim you can deduct your donations. . This claim itself is illegal. If people make large donations and deduct them, they can be prosecuted for IRS fraud later.
Even if they were lied to. The IRS and law requires each person making donations VERIFY for a fact that the donation is lawfully deductible. Something is wrong with all this.
There simply is no basis for any of this companies claims it is a charity to be true,. .
