Frustrating

<p>Bought a new phone with vodacom and I required a nano sim due to it being a later model than my previous. Therefore I requested a sim swap. They put the airtime through to the correct number but not the correct sim card (the normal size old sim cards). I called customer care they could not help me. They said I must go to the store. I sorted that out now I cannot see who is calling me. Why do they not tell you all of this at the beginning. Now I have to go back to the store and sort this out as well. Really unprofessional. </p>
