Vodacom Upgrade Fail

My next due upgrade with Vodacom is February 2019, but my phone is broken and I require urgently a new phone. So I phone Vodacom on the 11th of November to upgrade my contract early, first they tell my I can't upgrade so early because I don't spend more than R2000.00 a month with them, then when I tell them I will then have to cancel my contract in order to get a phone somewhere ells, they are suddenly willing to help me upgrade. So I placed an order on the 12th of November, they send me the confirmation sms which I rep**** to confirm, and they say it will take 3 to 5 working days. On the 14th of November I still haven't heard anything from them and phoned again, they say the order was not confirmed, I have to wait until someone phones me back to confirm the order. On the 15th someone phones me to confirm the order and again they say it will take 3 to 5 working days. On the 22nd of November I still haven't heard anything from them and phoned again, now the excuse is the phone is on back order, they don't have it available in that colour (black). After a long debate I change the phone colour to grey as that is the colour still available, and the lady promise the phone will be delivered at the latest the 26th of November. On the 23rd of November someone from Vodacom phones to apparently confirm the order and the delivery address, which I did again. The man promised the phone will be delivered on the 27th at the latest. On the 26th of November I still haven't heard anything from them again and phoned AGAIN. Apparently the phone is on back order, they can't tell me when one will be delivered. So its been 2 weeks, still without a phone and all Vodacom does is make empty promises. Vodacom is always so quick to spam us with all their products they want to sell, but when it comes to real service delivery they absolutely suck. I'm so frustrated with them and truly disappointed.
