Thank you for the suggestion. Unfortunately Lifemiles would not do it.
"
Let us inform you that once mileage had been credited in your LifeMiles account, the transaction can't be reverted, as per established in the Terms and Conditions (username and password are needed).
Due to the aforementioned, we can release the miles from your LifeMiles profile."
Any other options at this point?
