My suggestion would be to be patient - it has barely been two weeks since the end of November, some companies can take a while to tally totals and cut checks / make payments. Give it a month or so before posting about it, you could also contact them.
EDIT:
From DomainSponsor.com:
Why haven’t I received my payment?
All payments are issued by the 7th of each month.
Paypal payment can take up to 3 days to process.
Wire payments can take up to 10 days to process, depending on the number of intermediary banks and their location.
Checks can take up to a week to arrive in the mail.
NOTE: If your account does not earn the minimum payment amount set on your account you will not receive a payment. Once your account reaches the minimum, all outstanding revenue will be paid.
