Refurb phone in shop swopped for another refurb

I booked my phone in the customer service department @Menlyn for repairs. After 3 months i had to enquire about my phone as they could not track it. After complaining, a guy called me from the repair department in Menlyn and told me that my phone was exchanged for a new phone. When I got there, my phone was exchanged for refurbished phone. I was not happy as my phone is hardly used and now I was given a second hand phone so they sent it back to the advance repair only to be exchanged for another refurb? My phone was there for 3 months why was I not informed about my phone and whether I wanted my phone to be repaired or if I would prefer a refurbished phone. I want my phone and not some phone that failed the test without leaving customer care.....if you check ur records you will see that the handset spent more time in repairs than with me.....ABSOLUTELY ANNOYED AND FRUSTRATED. I have upgrades due with Vodacom but I am seriously thinking of joining a new service provider..pathetic service.
