Service declined

I called in wanting to know which doctors in my region is on the extender and service was declined aa I needed to confirm details I want general information why should I confirm details when I ask to speak to manager I am put on hold for over 5min until I wns the call. What kind of service is discovery offering to us. I waited for more then 8min on the line and the IVR doesn’t even give an indication what number one ia on the line. Really poor service
