Discovery - pillar to post, rude and unresolved. simple authorization required

One star is me being generous. I called in to discovery (whom is paid ON TIME every month, for a number of years) to get authorisation. i am pushed from pillar to post, speak to 3 people who keep asking me the same questions and then sending me elsewhere, and by the time i am in the right place, after speaking to numerous people, i am put on hold by an agent who leaves me there for all eternity and eventually cuts the call. this is after being on the line for more than 30 minutes trying to get authorisation. I then call back and ask to speak to a manager to escalate the matter. Enter Wanita, escalations manager who is so exasperated while speaking to me, no sense of customer centricity and snappy on the phone. When I bring her attitude to her attention, she sarcastically tells me "that's the way i perceive it". What a joke, in total almost an hour on the phone and still no authorisation. if Discovery bothers to look at this or reply, i have the call recordings, hopefully someone is interested in coaching or teaching these people on a little thing called customer service. Highly frustrated and looking at Bonitas
