JonNYC, have you contacted only ValueMags? If so, I would urge you to get in touch with GoldPoints customer service.
In the pursuit of my missing 300 pts/$, I never dealt with ValueMags at all...I dealt strictly with Goldpoints. From reading what others were posting here in Flyertalk, it seems that GoldPoints holds all the cards. ValueMags does little more than forward your requests to GoldPoints.
The number for GoldPoints is 1-800-508-9000, dial 9 for customer service during business hours. After hours you will only get an always full voice mail box recording.
