Bad Service

I took my Sony Xperia AQUA in for repairs to the Autopage Hillcrest branch. Note that this is the second Sony Xperia I received on this contract as the first went faulty after one day. I received a sms to collect my phone and when I went to collect it was told that the phone had been repaired. Upon inquiring what was done, the assistant checked the system and I was informed that there was no job card and therefore no work was in fact done. The assistant then went into the back of the store and on her return indicated that the reason the phone wasn't repaired was because the phone was not the same as the one on their system. I asked her to check again and she once again disappeared into the back of the store only to return and inform me that the phone was not repaired as it had water damage.<br> Well the name of the phone is an AQUA and is advertised to be able to take pics under water. More interesting though is the fact that the phone has in fact not been anywhere near water. Please don't intimate that the covers were not inserted correctly after charging as this is carefully done.<br> I need some urgent feedback as to what is going to be done, without the nonsense above please.
