Missing SD Tray

I took my cellphone into the Goldenwalk branch to be send for repairs on 23 Jan 2016. Zanele the consultant did the booking, however she did not remove the sim and SD tray. I was called on 8 Feb to fetch the phone but she notified me that they did not return my Sim and the SD tray with the phone. I told her I dont want the phone incomplete as I need to use both the Sim and SD tray to insert my sim and memory card. She promised to get both back and I decided to leave the ohone at the store. A week later I went back to enquire and she said the Sim tray arrived without the SD tray. I took the phone but insisted that she wrote a note which she signed and stamped that I took the phone without the SD tray. To date I'm still without a SD tray, a Mr Anwar Buckus who she corresponded with that if I treathen to cancel my contract its ok because the store is only a \franchise\". For the past month I have received absolutely no calls from the store informing me on progress, I have to go in and enquire. I have the right to cancel my contract for this phone as my phone is incomplete, I cant upgrade my apps, download etc. Customer service I received is pathetic. This is my 2nd complaint on Cell C."
