Testimonial Feedback Executive Services

I am looking for a way to speak with the corporate offices or executive services regarding my experiences with ATT. I have had such an incredibly positive experience with ATT in regards to my account that I wish to have that feedback heard by someone other than an agent or supervisor in the call center. While they have not always been able to accomidate my every request, I am an average person who has had an exceptional experience. I am quite thankful that ATT is my carrier.
