Appalling Attitude from Technician

With the title of my review, you would expect this to be a single star. However, I will rate it 2 just because my experience with Vumatel up until today has actually been really good. I had my fibre installation into my home scheduled for today. However, the technician they sent through had the most appalling attitude! He (Oliver Kabandi) treated my wife like trash. So she came to get me to step in even though I had a migraine. So I came to find out what the issue was. Turns out that it is too difficult for 2 grown adult men to shift a few items out of the way (e.g. about 15 to 20 roof tiles, 1m of palisade gate a plastic bottom of a cage). My 10 year old son could have moved these in about 2 minutes on his own. But when I tried to talk to him, he just spoke over me. Even when I asked if he would wait and let me speak, he shouted over me. As they are on my property and I'm paying for their service, shouldn't I at least be allowed to talk?? I eventually kicked Oliver off my property. After 20 minutes on the phone, Zaheer (co-ordinator) finally organised for a new technician to come tomorrow.
