I orderd a black friday deal after call center agent said it would be deliverd in 3days im still waiting

I placed a black friday online aplication on 24Nov. I recieved an order num ********** ********** 15. I did not hear anything after online aplicatiom said it was aproved and i have to wait for a call centre agent to phone me it took longer than a week for somone to complete my order. It was 6Dec to be exact. On a wednesday. The calm centre agent confirmed the order wil arive by 8Dec on the friday. It is now the 19Dec and i stil have not recieved my phones. I have sent severral emails with no response when i phone the call centre they just tell me they dont have stock and i must wait until stock arrives. My bigest problem is that my delivery adresse is my work place. And i went on leave 15Dec i asked the lady to just change the adresse and she said she could not i must wait for a sms for delivery and then phone in to call centre and as everybody knows that takes up alot of time. One of the phones is a Christmass pressent for my mother who left on sunday without a christmass present. And the other is for my daugter. But the funny thing is that when i go to the stores they have both tbe phones that i have orderd. But it seems that i will have to go else were to find christmass pressents. I promised my mother a new phone for Christmass and now she left without anything. I am realy disgusted as i am a customer of vodacom and i have been for years. But i realy thinking of migraiting to another network provider. And of i ever get hold of the call centre i would like to stop the pending order... i realy would never do busness with vodacom or ever rever anybody to them.
