Pathetic upgrade experience

I phoned Vodacom yesterday (wednesday) around 8:00 to arrange for an upgrade. I was told that confirmations would phone me a bit later, and that my phone would be delivered on Friday. I phoned upgrades around 16:00 yesterday to enquire why nobody has phoned me yet, and I was told that they would ask confirmations to phone me urgently. This morning at 8:00 I phoned upgrades again since nobody had phoned me yet, and again they told me that they would ask confirmations to call me urgently, and told me that I would still get the phone on Friday I they called me before 12:00. I phoned them again now (13:20 on Thursday) and asked why I haven't received a call yet. I was told again that they would ask confirmations to call me. I then insisted to speak with the team leader. After about 5 minutes, the operator (Phiou) told me that her manager told her that I would not get the phone by Friday. I then insisted that the transferred me to her manager like I asked before. She placed me on hold for 15 minutes. She then told me that her manager (Christina) said that she could disconnect the call, since someone would phone me. Obviously Christina feels that she is too important to attend to customers. it is clear to me that Vodacom doesn't care about customer service at all. I need someone who actually knows how to treat a customer to phone me and ensure that I still get the phone by tomorrow as initially promised. I don't care how you do it.
