Incorrect sim size

I went to perform number port from Cell C to Vodacom due to Cell C's poor network coverage but little did I know that Vodacom staff would welcome me with poor service. I went in and gave the service rep my iPhone 5 and he gave me a micro sim instead of nano sim, today I went back in hopes they would exchange the sim for me but they refused and blamed the whole thing on me. They insisted I should buy another sim pack and out of principle I refused because I felt it was their fault so why should I pay for their fault. The guy who helped went as far as shouting at me and I just stood there and listened.<br> <br> I now have a Cell C sim that doesn't work and a Vodacom sim that won't fit in my phone not to mention I'm now contactless. I very disappointed at Vodacom and also that there was no number for a manager at the shop!!!!
