I had my medical in Early Nov last year, sent all the credit card details along with it so that it would go through without an issue. Changed my credit card in Late Dec. Received my medical in mid Jan. Received a letter from CASA, in late Jan, saying that my credit card details where incorrect and that they wouldn't process my medical until I paid them....
Wouldn't know their @rse was on fire until you told them. Even then they'd probably not believe you!
