@Pauline ******
My bank told me the amount they attempted to charge the card was CAD$5430. The price of the policy in baht is 5430.
Instead of converting it to the correct amount in CAD the payment gateway they use has just changed the Baht to dollars and kept the same number.
My bank said there is nothing blocked but the attempted charge was just more than the daily limit for card purchases.
How did you end up paying for it?
