Disgrace of a company

Never in my life have I seen a company that has poor service like this one Vumatel and HomeConnect since Thursday last week we had no network.. I called on Friday was advise it an outage and by 17:00pm it will sorted, came Saturday still no network, called again and ticket was creadt and I got a call confirming that a technician has been dispatched to assist, till to date he has not come, I called today was advised they couldn't come because they didn't have cables.. And I'm wondering why they gave me a call. I have requested to speak to management and was advised I can't.. If only I knew they have *** service like this I will never have signed up with them.. There is no communication sent oyr when there is an outage but when the is a increment u get thousand sms..
