Useless excuse for Customer service

On the 28th August I took my Samsung s5 in to have the screen repaired. I took the phone into Dion wired in Gateway, where I was told the repairs would take 7-10 working days, while the s4 can be done in an hour. <br> <br> I am a businessman and my phone is my contact to my clients, and management. After a week I was called and told authority was required for a software upgrade to be done before the repairs could be completed, which nothing was done on my phone for a week. A week later I called again and nothing was done, this was the 14th September, well passed the 7-10 working days advised in the beginning, now another two weeks later going on 5 weeks since I took the phones in for repairs nothing has been done and we are \still waiting for parts from JHB<br> <br> I need a call from someone in charge to call me to explain what kind of mickey mouse business you are running. You were in my opinion the best electronic s manufacturer in the world
