Poor quality of service for phone repairs

My LG Leon phone was booked in for a cracked screen and a camera that was not working. Firstly we had to make three trips to the store to get the phone booked in due to the \changing times\" of the repairs person who never seemed to be there. Finally the phone was booked in and a week and a half later, i received an sms to pick up the phone which I did and was horrified to find that the PHONE SCREEN IS STILL CRACKED even though I have screen insurance. I was not given a report on repairs done but was told to make a payment of R57. I called the store back and was told I must once again make the trip to have the phone booked in for screen repairs , unconcerned about my inconvenience of keep making this trip and once again having to rush to make the times the repair person is there!!! This is a horrible level of service and of course its not easy to report bad service either."
