Since my card expired and I changed my payment details to my new card, my payment keeps getting declined. I think it's because I can't input my address correctly, it asks for a house number but I don't have one. Could I get my address changed so my payment goes out correctly?
Perhaps try again using a different internet browser or using your browser in a private window or incognito mode.
Also maybe this time try 0 0 0 (three zeros) for the house number if you don't have an allocated number at your address.
