Urgent Request for Sales Assistance - Workfront Proof Inquiry

I am writing to bring to your attention an urgent matter concerning my interest in obtaining Workfront Proof. Despite multiple attempts to contact the sales department, I regret to inform you that I have not yet received any response. 
I also tried the support center but they failed to assist me also.

This lack of communication has impeded my progress, and I kindly request your immediate attention to address this concern.

Could you please assist me by either providing the necessary information regarding Workfront Proof or directing me to the appropriate contact within the sales department? Your prompt assistance in this matter would be greatly appreciated.
