Poor service

I upgraded almost 2 weeks ago, but the device was out of stock. Last week I got a message that they have stock and will deliver shortly. On Monday the courier tried to deliver, but would not allow my wife to sign for the parcel. After phoning Vodacom and explaining that I am out of town and my wife need to sign for the parcel they said that they will allow it and someone will phone me the same day to confirm. The lady also said that if I do not answer the call from Vodacom, the third party delivery will be canceled...... So I have been waiting for more than 72 hours now for a confirmation call, while the courier is trying to deliver every day and haven't received an instruction from Vodacom to allow my wife to sign for the parcel. I have been trying to phone Vodacom, but get transferred left to right and on average after holding for 20 minutes they drop the call. It seems that as soon as you agree to extend your contract.... The customer service goes out the window. Absolutely pathetic
