Wrong sim card size given

Went in for a sim swop from MTN to CellC for my wife, who accompanied me.<br> Filled in all the paper work and told the lady that the phone was a Samsung A3 needing a Nano sim card even showing her the phone.<br> When the message came through that the new sim card was activated we attempted to insert the sim card which was the wrong size, although we told the sales lady what we needed, <br> I went back this morning The same sales lady said she was sorry and gave a new, right size sim card. Now this time my wife was not with me, but the lady said I should phone customer service at 140, they would sort it out which I did, <br> There after a whole lot of questions asked, and twenty five minutes on the phone they told me I must go back to the shop and they must sort it out.<br> Now, I wonder what kind of customer service that is? I have to go back to that shop for a third time.<br> That gives me the idea that they really think nothing of their customers time, they don't care about how much it costs you get there 3 times and the amount of money I spend on the phonecall.<br> <br> Then they have the audacity when I put the phone down to ask me to complete a survey on how I rate their service
