Poor Service

I called through on 2 Mar 2016, for an upgrade on my phone. I received my phone on Thursday 3 Mar 2016. Lovely service...... I was told on the phone call on the 2 Mar 2016 when doing my upgrade that I will need a NANO sim. Expecting the Nano sim in the box with the upgraded cell phone, it was not. I called immediately on the 3 Mar for the NANO sim, I was told that the order was not put through. I have had the run around for 3 days including today being Monday 07 Mar excluding the weekend. They have passed the buck to back office which never contacted me up to today. What should I do with an upgraded cell phone and no NANO sim. I am extremely unhappy with the service after 15 years that I have been with Vodacom.<br>
