Shouted at by agent

On 19 February at around 08:25 I had the unfortunate experience of dealing with a Dstv call center agent named Catherine on the 012 number. She was extremely rude to the point of actually shouting at me midway through the call. I asked to be put through to her supervisor and she put me through to a guy called Sibusiso who said he would listen to the call and get back to me. Its been 2 days now and still no word from him. I suspect she put me through to her buddy and not her manager. At least I hope because otherwise it means Dstv does'nt give two hoots about their customers. What I experienced was extremely unpleasant and hope no other customers have the unfortunate experience of dealing with that rude little girl.
