Why use vodacom phone insurance???

Saturday the 17 October My phone was ****** from the Gym. Monday. On Monday I received a phone call from Vodacom informing me that I could go to any Vodacom shop and pick up my new phone. On Tuesday I went to the Vodacom shop in Rosebank but they said they did not have a phone to replace the one that was ******. I received the phone (a windows Lumnia 8?? ) from Vodacom on contract about 6 months ago. I then went to the Vodacom shop in Hyde Park and was told that the nokias are no longer available and that I wouls have to pay about R3000-00 to get a replacement phone or alternatively I would have to buy my own phone and send them the bill. This is totally unacceptable as I have been paying higher premiums to be insured by Vodacom so I have to use that I can avoid these problems and get my phone quickly. I am leaving for an overseas trip this evening and I am going to have to use a inferior phone.
