Poor Service

On the 08th Jan 16 I had taken my cell phone in for repairs to the Samsung Smart Care Service Centre in Century City. I was told that it normally takes 24 hours to fix the cracked screen however they did not have parts available and advised that it would take +- 3 - 5 days. On the 14th Jan I called to ask if my phone would be ready by the Friday and was told that they had not ordered parts yet and that my phone will be fixed the following week. I called again on the 20th Jan just to be told that they hadn't ordered parts yet! I asked to speak to a manager and kept being told that the managers (2 of them in the store) were busy. I then sent an email to their complaints department on the 20th Jan and to date have not received a response. On the 22nd I called to ask if I can fetch my cell phone and have it fixed at the corner shop were I can expect \not such excellent service"(I actually now compare Samsung to the corner shop). I was told that my cell phone was fixed and ready to be collected. How come it took them 2 days from when I last spoke to them"
