Poor service

On the 0 4-07-2017 I took my phone for repairs the screen cracked at Markhams in Springs Avenues, I have phone insurance with Foschini groups, I went to check on the progress after 3 weeks nothing was done and the phone is still at Markham in Springs, again I went to Markham on the 22-08-2017 my phone is still with them at Markham in Springs, when I asked why is the phone not yet repaired they made a phone I am not sure if it was Foschini group they told the staff at Springs Markham that the repair has been authorized, only to find out that no arrangement was made to take the phone for repairs, no follow up was made by staff working at Springs Markham, I am very disappointed and disgusted by the poor service I received at Markham in Springs Avenue, my request is that when hiring staff can they please take their staff for customer service training. I am very unhappy
