I don’t know how to contact khan academy so I have to use Twitter... I set a credit card for donating to khan but my mom cancelled my credit card a month ago and I forgot to reset a new one. There were three message sent by the bank saying that khan tried to use my credit card
Hi! Thank you so much for your continuing support! If you could send us an email to donate@khanacademy.org we can certainly cancel the credit card donation! Thanks again.
