Hypa Fibre

Good day, I signed up with an internet provider Hypa Fibre, which they have a contract with Vumatel. Vumatel scheduled an appointment with me for 11th November @ 15:30. Yesterday there sub contractors pitch up at pass 1 o'clock. They had to make a whole by my next door and he was not at home, just before 15:30 the contractors decided to leave because they couldn't wait for the neighbor and my husband told them they must wait 5 to 10 minutes, because there appointment was half pass 3 and not before. The contractors than logged an appointment with Vumatel for 9 o'clock the 12th November, no phone call from Vumatel. I waited till pass 9, went to work late, due to waiting on them. I then phone Hypa again and then they saw on the system that's Vumatel re-schedule again for the 13th @ 1 o' clock, not informing the client. My question is how do they know if we have people at home and how can we just stay home to please them. The worst part is, we are a new client of Hypa Fibre and first time Vuma installation, so sad. Very poor sevice
