I'm guessing that this is related - issued a partner award on 23Nov and cancelled it a few days later, choosing to pay the 12k miles for fee instead of $s.

I see the debit of the miles for the award, as well as for the redeposit fee, and the taxes/surcharges credit is there on my card already - but, not the refund of the miles for the award. A few emails exchanged with the club (including a new 'verification' over email - the same Qs that they ask on the phone), and after an initial 'Refund of the miles was reflected in your account on XXX', I get:
"We would like to confirm that XXX Asia miles have been credited to
your membership account on 28 November 2018. However, due to a technical
issue, such transaction details has not shown on your transaction
history.

Our technical support team is aware of the problem and it will be fixed
soon. The transaction will be reflected in your monthly statement of
January 2019. We sincerely apologies for any confusion this may have
caused."
