Terrible customer service

I refuse to believe that a company as big as Discovery does not have an effective customer service department, I am not certain why I am experiencing such horrible service from them. I have about 4 products with Discovery and have serviced them very well but Discovery hasnt kept to their end of the bargain. My attempt to add a fifth service was blatantly ignored, when I called to follow-up and also update one of my covers the consultant dropped and never bothered to return the call, I was already authenticated and he had all my details. Thank God for Outsurance's amazing customer service I was able to get the cover I wanted. I have checked the App for a place where I can request for a callback to update my cover and did not find any and since my attempts to communicate with Discovery through their website and call center yielded no positive results I was left with no choice but to write this review. Discovery needs to do better in their responses, especially to their existing clients.
