Vumatel : worst customer service

I needed home Fibre so I was contacted by vumatel, I was sold on the product after being told about the quick effecient and timeous service...... What a load of hogwash. My installation was scheduled for Monday at 9 then changed to Monday at 12 then mysteriously changed again to Tuesday now a whole different day, I had made arr for someone to be at home on Monday at 9 now I have to pay someone for another day 😔 I am frustrated and at my wits end being told there is no one I can call or email in this regard. I think vumatel need to up their customer service and interactions. I am appalled
