Honeyfund Issue

Honeyfund users please help!

We made our honeyfund so that it would be 100% free. Our settings are that guests can't pay with credit cards, which would charge us a fee, they can pay via cash/check or venmo. So far, all guests have paid with credit card and we have no way to retrieve our funds. I think we have to allow credit card transactions in order to get the funds, which defeats the purpose. I'm wondering if this is how honeyfund scams? I even went to our honeyfund page as a guest and saw that the only option honeyfund gives is to pay via card.

I called them 3 times at different times of the day today, and each time the message says all lines are busy, please leave a message and we'll get back to you. Sounds suspicious to me.

Anyone else use honeyfund 100% free? Anyone else ever able to get ahold of them on the phone?
