I want my phone!

I'm very upset because of Telkom. They gave me tracking number last week thursday but they have NEVER handed my phone to the couriers. On thursday they said friday. On friday they said I will have it monday, on monday they said tuesday. On tuesday they said thursday but even now they haven't dispatched my phone for delivery! This is the worst service I have ever come across. Don't tell me u are sorry for the inconvenience. just send my phone today or tell me how to cancel this contract. I refuse to wait until next week again. On the 28th u will be debiting my account again for a phone I have used for 1 week and that is if I will even have it! Call me today I don't care if it is to bring my phone or cancel this contract. ***.
