Cant change my country to update payment method

[grunticus]

Hello,

I was trying to update my payment method from a NZ credit card to a US debit card however it asks me to change my country in order to do so. When i follow the link it takes me back to the start of the change payment option page (not useful). I have also looked on the support page how to do it. It talks about getting to typing in your new details and clicking on the "..." button however there is no "..." button to click. 

My country remains greyed out and wont let me change it. 

Help I need my music to make it through the day 😛
