Paymentwall blocked me

yeah so paymentwall has blocked me because i accidentally use a saved card on google crome that expired this month and i forgot and now it wont even let me enter a new card it want all this info about the other card and i just wanna donate lol please can you help

Either use a prepaid card (Mint, Subway, whatever you have available) or contact paymentwall's support, Warmane has nothing to do with the banks or that part of the donation.
