Vodacom must close their doors

I have upgraded a contract that was due for upgrade. When we switched the devise on it was not working. I took the device back and it can not be swoped for a new device. Vodacom policy states that the device needs to be booked in until a credit can be done then only a new device will be issued. This transaction is taking a week whereby they just notified me that it will only be sorted out in the coming week. Vodacom will credit my account with the full contract amount whereby i only had service on that contract for two weeks. This is not my first poor experience from Vodacom and i will never recommend them to any one. PLEASE STAY AWAY FROM VODACOM!!!!!
