Here is a mail I received yesterday from Goldpoints CS. It doesn't address the reason why the partnership was stopped or if any outstanding points will be credited but I have asked for further clarification and will post here when I get a reply.

Thank you for contacting Gold Points Rewards regarding our website.
Unfortunately, Giftcertificates.com is no longer a Gold Points Partner.
I apologize for the inconvenience.

Thank you.
