Wrong Sim Card

I received a new Blackberry z3, but the sim card was the wrong size. Took my phone into Vodacom and received a new sim card. Emailed the invoice to Mondo customer care and within 10 minutes, received an email to say that the cost of the sim card will be refunded. A few minutes after that Kimona telephoned me to confirm that the refund will appear in my Vodacom account within 72 hours. I was very impressed with how quickly and professionally my problem was handled. Kimona was both pleasant and efficient. What a great experience.
