If you have entered your credit card, but it keeps returning to the same form, please verify that:
a) You are using a registered credit card (Note: American or Canadian VISA or Mastercard only). A prepaid credit card will not be accepted until you have it registered under your name and address. (Please check the details is on the back of card or check the card's website directly.)
b) Make sure you are entering all the information correctly. If you are redirected to the same form again, please check if there any 'red' marked errors.
c) Double check that you have entered the correct expiry date.
d) If you double click when adding the card you may get an error message. (so best not to do that!)
e) Delete the card, and try again.
f) Contact your credit card company and see if they have marked MaxSold as spam.
If any of above doesn't work, please contact MaxSold Support immediately at email@example.com and we will check the back end system for you. Thank you!
