Worst Customer Experience

My initial intention was to upgrade my membership, then i waited for 17min and 10 seconds when Trevor answered i expressed my frustration because of their turn around time was extremely poor, i then asked to speak to a manager, Trevor then said it will take a minute hold on, i spoke to Trevor for less than a minute, and was put on hold again i waited and waited and waited and waited until 35min still nobody was on the line. I will definitely be cancelling my membership with Discovery, after 10 years you guys maybe half a million in premium. Im Done with Discovery. Extremely dissatisfied customer.
