Furious client *********** staff

So i called into telkom call centre in Cape town.. spoke to Asabonga. Explained to the agent that I bought a mo'nice bundle at round about 8pm and downloaded 1 episode and when i woke up my data was depleted this agent advised me that my data depletes fast because my data usage is to high! Firstly what does my data usage got to do with anything? Then she came with the excuse that I used all the data lady I just told you I switched off my data after downloading the episode she even placed me on hold for a max of 20minutes without even asking me if it was okay to put me on hold the phone literally just went blank so who is telkom employing these days??
