If you're going to use credit card payment please be aware of this: If a card is declined > the only way to resolve this is to reach out to your their card-issuing bank to look at the transaction and determine why it was declined. Provide the bank with the charge amount, date/time, and the company name (in our case we use mivon.org as no one wants to see " steroids " at their statement) for assistance. Then, feel free to try again. Or tell them to await such charge to go through soon and then try to pay again 🙂
