Totally Outraged and Disgusted

My fiance purchased me a pink Blackberry 9720 on his account at Edgars Claremont on 5 February,I didn't have any problems untill a few weeks later I wanted to take a picture & there was a line right across,it was the first time I was using this feature as the phone was still brand new and barely a month old I took it to the nearest Edgars.Spoke to the Cellular consultant Andy who assisted me & had it booked in at Vodacom's repair centre.I was eventually notified via sms that my phone was repaired after 6 weeks.30 April I collected my phone,another consultant assisted me who wasn't very helpfull,she just gave me my phone as if to get rid of me,only to discover that it was not my phone but rather a refurbished 1.My disgust & horror as I felt cheated since my phone cost R1,899 & is brand new only to be replaced with a piece of **** that I'm having endless problems with now.I feel outraged as I wasn't informed,went back the following week & spoke to Andy who appologized for her colleagues incompetence but didn't explain why I got this phone.I demand to know where my phone is or get a brand new 1 or I'll take it further.As this 1 is very old according to the battery & the way it handles
