I tried to buy tokens on camsoda via paypal and my Visa card. In return, I got this message: “we could not process your payment”. It appeared that my camsoda account had to be verified. J had to upload my driver license and my a photo of my credit card hiding all the numbers with a finger except the last 4 digits. so, if this happens to you, contact the camsoda support team. They will send you a link to the verification page. If the problem remains after submitting your documents, contact them again.
