Switch account to the other country, but the payment seems have problem

[jinyu204]

Hello,

I was a UK Spotify user, and now just move to Taiwan.

I know I can change the region by update the payment to Taiwan credit card.

But the subscription fee doesn't switch into Taiwanese charge, NTD 149, it charges me in British pound or NTD 223.50 instead.

(I own student discount in the UK, which is around £4.XX / M , I wonder that is how the number NTD 223.50 comes from )

Now I want to switch my account as a Taiwanese account and pay as the others, NTD 149/M.

Could anyone please tell me how to do? 

Many thanks,

Ps. Another question: I connect my FB account with Spotify. My date of birth on Spotify account is wrong, but I can't update it in Spotify system.

I do check my detail on FB, they are correct. Could somebody also teach me how to fix this? thank you.
