AWFUL Upgrade experience

I was super impressed with Vodacom's service and delivery last week Wednesday (09.03.16) when I received my new iPhone 6. Disappointment hit me when I opened the box and there was NO NANO SIM. I called the upgrades department immediately and was informed I would receive it within 2-3 working days. This is now the 4th working day.... and still no nano sim. They can't even find the order on the system. I called yesterday and the agent assured me I would receive my sim today. This is my 2nd call, to Vodacom, and I'm now on hold for yet another department to explain my story 4 times in 2 days. REALLY??? I've been with Vodacom for the past 14 years... It might just be time to take Cell C up on their buy out offer. ALL I WANT IS TO COLLECT MY NANO SIM, and not pay for it!!!!
