You have to use the exact address,postal code and state
And I don't think it's all banks that can be added
For example,I was able to add my fcmb master card to playstore but I wasn't able to do it withy kuda visa card
A debit fee will be collected when linking so make sure you have up to like 1k in the account. I don't really remember how much I was debited but it wasn't up to 500

I will give this a try
