Worst Service Provider

Please explain to me why 2 appointments from Vodacom to resolve my fiber not working were not kept and I was not phoned. Why numerous emails with reference numbers have not been responded to and why after 3 calls to Vodacom at last I get assistance being told whole system is down in our area and it is being resolved? When? Why no reply on emails or phone calls? why is wifi not reactivated while problem is resolved. Payment deducted so is a credit going to be passed for off days? Vodacom is in breach of contract please give me a valid reason not to cancel? Bet I will get automated response saying will receive call from Vodacom that NEVER happens.
