10 weeks to repair cellphone

I booked my device in for repairs on 29 June 2015. I received it back but there was a hair under the screen. It was booked in again. When I received it back it had the same faults as before. I re-booked the device and when it came back it still had the same faults. I then booked it in for a fourth time on 28 August 2015. Apparently it was repaired by the Advanced Repair Center and sent from Bethlehem to Kroonstad on 2 September but it seems the courier is taking detours as it still has not arrived in Kroonstad which is 140km from Bethlehem. <br> <br> I find it unacceptable that I have been without my device for 10 weeks (i.e. 10% of the contract term) although I am paying for it every month. I am not even sure that when I eventually receive my device that it will be fixed.
