Terrible service

On the 13 of May 2015, I took my cellphone in for repairs which I had taken out with the supplier less than 2 months prior when the touch screen just stopped responding. I had to wait about an hour before I was assisted because I was told the guy who books phones in was on lunch and that he was the only one who could help me. Eventually the phone was booked in and I was informed that it would take a maximum of 16 working days and that someone would be in contact regarding the phone when it was ready. 22 days later and 16 working days later no one had been in contact with me so on the 4th of June 2015 I once again visited the cresta branch again having to about 40 minutes in line. I was informed that they were waiting for a screen to be delivered which nobody had informed me. I am still without my phone almost a full month now yet I am still paying for it every month.
