We appreciate you reaching out regarding the transfer overage charge that resulted from the malicious traffic. We understand that these things happen and are happy to work with you here.
I went ahead and issued you an account credit for $*.**. This is the total overage charge on your most recent invoice. This credit is non-expiring and will go towards future invoices. Our billing system will deduct from this amount in advance of any attempts to collect against your primary payment method.
I hope that this was helpful. Please let us know if you have any other questions or concerns.
