Agent Name "James" encouraged me to switch to AT&T

Ive been a customer for over 10 years and always cringed at the idea of calling into for support since I always get pass to people who try to sell me something instead of helping  me with what I am asking for. After the agent named "James" wasted my time for 30mins I kindly asked for a manger or supervisor. James wanted to know why I wanted to speak to a manager and declined to do so. He did not want to identify the call or his id number or any factor that would identify the current call vs others. Thanks James and to all the other employees who offer low quality customer service. What I wanted was simple. Just to switch to a different plan.
