Value your clients, you promised good service, but you don't.

I've been a client of Vodacom for years. When the due date for payment arrived, a different amount was debited even though I had been informed that a different amount should be deducted. The next month it increased from R811 to R874 to R923!! I have reached out for assistance on numerous occasions. Vodacom frequently informed me that the contract could only be terminated after the device was returned. The device has been returned, but I'm still having trouble getting the contract cancelled—something I never wanted in the first place! I have been charged for a new phone, which I never received. For the past three months, I have been trying to get this contract terminated. I am so tired of this ongoing saga.
