Poor Customer care

We live in a competitive day and age. Discovery's customer support is of the lowest I've experienced. Kwandiwe was rude, with hints of sarcasm and had no intention to help resolve the issue at hand. An infuriating experience and I'd strongly recommend avoiding Discovery until they improve their customer support. Also to mention, I could hear personal conversations in the background, giggling etc. Very unprofessional. Lastly, I was told I failed one verification question, which means I got 68%? How is 4/5 68%? Kwandiwe's response was "What does 3/5 give you" - he was hoping 68%.
