Delivery new handset upgrade

Second time dealing with skynet. I get a text now at 20.00 to say my delivery failed. Why did it fail? I been home all day. I specifically asked vodacom not to use your company because of bad service. If my parcel is not here tomorrow then sorry for you. You can tell vodacom I will be overseas and the customer will cancel because of poor service from skynet and if I am charged by vodacom for goods I dont have I will promise you I will see you in court as I have previous emails on previous delivery incompetence! On my initial call to vodacom I specifically stated NOT TO USE SKYNET. Vodacom go listen to my call!!
