My new iphone was damaged by Vodacom

My phone was sent in after 2 weeks since I bought it. I waited 6 weeks and it went back to Vodashop Pavillion while I was away and my wife collected it and was told all was working good. I arrived home and tested it and it was exactly as it was 6 weeks agao. I then bookedit in at Gateway and wiated 3 weeks to be told it now has water damage. I am back overseas working withou the phone no phone call from anybody and I dont even know were the phone is now. I feel like reporting it ****** at the police but they are just as useless as Vodacom. This will be the verly last contract ever with this useless company and I will still have to take legal action to try and retrieve my phone, simply disgusting service?
