It's time fo another informative and educational lesson brought to you by the best isiZulu teacher there is, Sky Tshabalala. Have you ever answered your phone and did not recognise the voice on the other end of the line? Was there a language barrier that prevented you from telling this person that they, unfortunately, had dialed the wrong number? Well, now, thanks to Sky, you can learn how to say: "Sorry, I think you have the wrong number." Take a listen and join in as Darren and Keri use their newly learnt phrase and call each other on-air.
