Hi there,
We're writing to inform you that your account has been frozen after a payment in its history was placed into dispute. You won't be able to access your account until this outstanding payment is repaid.
I'm afraid that we can't tell you why this has happened, as the individual payment providers manage all aspects of transactions made through them. For further information, and to arrange repayment, please contact them directly.
Once you have made repayment to them, your account will be returned to play.
