"Thank you for contacting The Marco Polo Club Service Centre.
This is to explain that mileage of your flights from Jakarta to Hong
Kong and Hong Kong to Toronto were credited to your account at the same
date, therefore, all your previous Club miles and sectors have been
reset to zero when your membership has been upgraded.
We are sorry that we are unable to credit the Club credits of your
flight CX826 to your current account as it has been credited to your
previous membership year.
8 July 2012 CX826 Hong Kong - Toronto
However, we would be grateful to record a remark in your profile about
this flight. If you incur a shortfall in next renewal, the above flight
would be taken into consideration. Please do contact us closer to your
renewal date if this might happen and we will review your membership
accordingly.
Kind regards
Ryan Wai
Customer Relations Executive
Membership Administration
The Marco Polo Club Service Centre"
See above the reply of MPC. Should I escalate or let it be? If I let it be, what is the likelihood I will be able to "charge" this in the next renewal or upgrade if I shortfall by this amount or less?
