Ebay Ebay requires personal payment equal to charity donation sale

I donated and sold many things to raise money for the 501(c)3 public charity. For the latest item sold, Ebay again deposited the proceeds into the charity bank account. Now Ebay is demanding that I make a personal payment to paypal equal to 100% of the amount of the sale that was deposited in the charity bank account. They will not take a bank check from the charity account. It has to be a personal payment. There was no mention, after an hour or so chat, of the charity ever receiving the money that has to be returned.  I asked many times why they wanted to have the sale deposit returned and whether they were going to reseposit it. Never got an answer. Just more demands that I personally return the money.
