According to the MR T&C:

5.2 Subject to these Terms and Conditions, if you cancel your enrolment, unused points may be redeemed for up to 30 days after the date of cancellation.

and

11.2 If you cancel the Primary Card Account and all Linked Accounts with us or if, for any reason, we cancel the Primary Card Account or any Linked
Account, any Points accrued in the Program Account will be forfeited and
will not be capable of transfer, conversion or redemption.

So looks like you are out of luck.
