Call centre is a black hole

I have been trying for the past hour to speak to a consultant at Discovery. The first time I held on for a lengthy period after which it just cut me off. I rang again and waited patiently, after some time it connected to on of their 'skilled consultants' which I could hear in the background talking to someone else but after shouting into the phone numerous times to try and get her attention with no response, I had no choice but hang up. I am currently waiting again... Seems like Discovery call centre resembles a government institution or a black hole. I grow weary of listening to the recorded voice instructing me to wait as my call is important to them.
