Most argumentative and unhelpful support agent.

I have a Microsoft Office Home subscription through MWeb. A few days ago I noticed that the subscription seems to have ended since I suddenly didn't have the 1TB OneDrive space available that is included in my subscription. After speaking to a helpful agent who referred me to Microsoft - who just confirmed that my subscription terminated on 24 Oct and that I should rather call MWeb to cancel my subscription and take one out directly through them. When I called back, I spoke to someone called Byron, who not only insisted that I only have a personal subscription instead of a home subscription, when I told him that I was most unhappy with his attitude and insinuating that I didn't know what I was talking about and to please put me through to the customer satisfaction survey, he terminated the call instead. I called MWeb back this morning and hopefully the matter will be resolved, but I think call centre agents like Byron should be taught not to argue with a client who knows what they're talking about and then become argumentative.
