Hello sarahlsmith1966! Thank you for your post and welcome to the PayPal UK Community! I am sorry to hear about this. You cannot set a default payment method on your account but you may be able to change it for individual payments. You can read more about this here https://goo.gl/SLnUvR. Please note that our internal security system might block some of the funding options due to security reasons. Unfortunately, this is not something that can be overridden. I recommend clearing cache and cookies from your internet browser and trying a bit later as this might help. Hope this helps. - Carlos
