2 months and no repair on my phone

I handed my Sony Z3 Compact in to Mtn Menlyn on 17 February 2016. <br> <br> The phone was submerged and the waterproofing failed. I was assured I'd be kept updated on the progress of the repairs, as they had to send it away. On Saturday morning I stopped by Mtn, who initially told me that repairs take 10 working days, to hear that the phone was sent back to the shop, not repaired, only to be re-sent back to the repair centre, who said that they need to confirm and test whether the waterproof flaps were closed, which were, as per the fault report that I wrote when handing the phone in.<br> <br> The phone was 8 months old, never previously submerged in water, and the entire inside flooded and the phone failed. <br> <br> I find this unacceptable, as the phone was marketed as water resistant up to 1.5 meters for 30 minutes! It was submerged for less than 2 minutes, and failed. <br> <br> I'd love some feedback on the matter, as the current service experienced is beyond appalling! <br> <br> Thank you
