No delivery for an upgrade

Good day. On 14 November 2017, I called Vodacom to upgrade my contract. I was helped by a lady named Nthateng. I explained to her that I had just lost my phone and I was in need of a phone, hence I decided to do a "premature" upgrade, 2 and half weeks before my real upgrade date. She was quite helpful and I was happy with what was offered to me. Understating that I am in dire need of a phone, she promised me that the phone and the new sim card (I suspended my sim after losing my phone) will be delivered by Friday 17 November. That was not the case. Today, being 20 Nov, I am still without a phone. I called in this morning to inquire about the delivery and I was told the phone will only be delivered "anytime from tomorrow", which is unacceptable. The reason is that I will be going away and I am afraid that if the phone is delivered "anytime from tomorrow" I will not have a phone. I ask that my phone be delivered today failing which, I see no reason but to cancel this contract. I have been a loyal customer of Vodacom since 2002 and canceling my contract is the last thing on my mind, but I will not hesitate to do it if I do not get my phone today.
