Very fraustrated

This is the third time now that my cell phone, Blackberry Z10 has been in for repairs, twice I have received a refurbished phone, the last one collected the Friday and returned the Saturday. I have lost so many valuble documents and my sons birthday pictures due to this on going problem. I have been a client for around 12 years if not more and the service is just going down. I was advised on the 24th Jan 2015 that they will excilate the phone to be replaced with a new handset only to now find out that they are gonna send me another refurbished phone. I have a few other contracts with vodacom as well and feel that with this service I SHOULD find another service provider. I do not want another refurbished peice of junk and not a no history device as they call it, its still refurbished in some way. I request this phone to be replaced with an inbox sealed phone or to be supp**** with a better Blackberry than a Z10 also sealed in a box!
