Apologies if I am barking up the wrong tree - but could there be a problem with the form of payment i.e. debit card? Remember "A form of payment could be a credit or debit card, a bank account, or a transfer of money to Google. Every country offers different ones, so be sure to explore the available forms of payment and payment minimums for your location."
Hope this is of some help.
Let us know how you get on.
