Almost 2 months without my phone

My cellphone was sent in for repairs in February and when it was returned it still had the same problem, I took it back to the store and it was booked in this was on 1 march 2016. To date I have not received any feedback regarding my phone and the progress of the repairs. I went to the store to query and was advised that they have no information but will follow up - this was 2 weeks ago.... A week ago I received a call at 17:00 requesting I return their loan phone urgently as the store needs it.... Begrudgingly I did so and was given another loan phone but still no information about my own cellphone.... It has cost me a fortune needing to reload applications on new devices each time and I am appalled at the lack of concern for customers from cell c. What further upsets me is that I had the same incident with my tablet being sent in for repairs and upon receiving it back the device had not been touched and I had to send it back to the repair centre. How is this possible? And why have I not received any feedback or SMS advising of what is happening to my cellphone. ...
