Purchase Problems / Anyone have advice?

in Game Issues
A guild member is having this problem (see pic) and asked me for my advice.
I have given a link to CAN'T PURCHASE IOS PAGE and told him to contact support with screen shot. I have also warned him that support will not likely reply till Monday. Does anyone have any other advice?
@David_H79 @zbot maybe?

I haven't used apple store in ages (being android) But i do remember getting (legitimate) emails saying i need to update my details in the apple store I think they like you to change password frequently maybe worth him logging into the store some time

This is from Apple but it's more or less the same thing on the support website.

@zbot , I believe he has but I'll pass all this info on and hopefully it'll help.
Much appreciated!
I never remember to update every location when my CC is renewed.
