Thank you for joining our Support Community to share your experience about the Black Friday promo. Having to call every month to get your bill straightened out is a hassle and I'm sorry you're having to deal with this. I'd like to think of myself as a billing guru but I'm stumped as to how one of the Pixel credits would simply stop showing up. It's possible that your account is being reviewed to have the proper credits applied which generally doesn't happen immediately. I highly recommend getting in touch with T-Force (our social media customer service team) as they have the necessary account access to review the promotion and credits. You can contact them by clicking the Facebook/Twitter icon in my signature or by going here. Again, I'm incredibly sorry you've been having to go through this for 8 months. Please keep us updated on the outcome after you work with T-Force.
