I am sorry about the surprise upgrade. Since you deleted the list within 24 hours and did not send to those contacts, this appears to qualify for the once-per-year cooling-off reversal. I will send this to Finance & Trust to confirm and process; I cannot promise the reversal until they verify the account record.

The customer is back on Launch.
