5 months no phone and having to contact store

On the 1st of December 2014 I booked my sony xperia z1 compact (advertised as water PROOF),with a few very slight scratches on the screen protector, in to the branch as my phone went into the pool and was liquid damaged even though I made sure all flaps were closed properly. I was told it would be sent away and assessed. The phone returned and lee told me that he would have to send it to sony as its a sony issue. He then sent it back to the cell c repair centre which took about another 2 weeks to get back, I then had to drive to the store after leaving 4 messages with different staff members as lee is never available to answer my calls ad never calls me back after requesting him to every time I call..when the phone came back , it literally looked as if people had been playing soccer with my phone. (The bottom speeker was loose , there were dents on every corner of the phone and scratches all round and was sent to sony in that condition. The phone returned to store and again I had to make contact with store with no responses again and hsd to drive out just to find out sony wont repair it.<br> I agreed to take it up with sony if cell c repairs what they have damaged.<br> To date no response
