Service way below expectations

Firstly I am IT clueless. I went into Vodocam at the Table Bay Mall earlier to buy an IPhone - to clarify, the store opposite Oxford Stationers and Pick N Pay. I'd already decided on the make and model. Well, I've never seen so much faffing around, keeping me waiting until various tasks were completed. It involved a Sim Swap and the purchase of a second Sim Card for another 'phone. I was in the shop for at least 1 and a half hours. I asked if my Contacts could be transferred to new 'phone. This was put in the hands of their 'Technical' person. Well he couldn't do it. In the end I walked out in sheer frustration. I'm home now with a 'phone that doesn't work. I don't know what to do. Terrible
