Unable to change my payment method

[#1]

I get the following error message when I hit the change payment method button : 'There has been an issue; please consult your system administrator'

I need to change my DD details, can we get this fixed please, don't really want to have to make a phone call.

Works in Firefox, but should really be fixed for Chrome as well.

I can pass it on to the relevant team if we get some more examples of people who are still having the issue. I will note it down on my side for the minute.
