Vodacom upgrade cancelled no reason no apology

I did an upgrade on my vodacom contract and received a confirmation email that my phone would be delivered during the week, the confirmation email was received on the 30/12/2019 - I called today as I did not receive the phone as yet. I spoke to Nomsa who told me its cancelled. No apology, no explanation, just its cancelled she will submit and it might come in the next few days. Really Vodacom??? Pathetic
