No service at Samsung Tygervalley Celluar Repair Centre

I took my Samsung Note4 to the Samsung Tygervalley Celluar Repair Centre on the 23rd of February 2018 for a repair. Jamey was on duty at that moment and booked in my phone after I explained the problem I have. Before paying the R228 assessment fee, etc. she explained to me that I would receive a call from a technician by no later than the 28th. However I had to phone them back on the 2nd of March. Jamey was not available but the lady who answered neglected to give her name. She did confirm that my phone was at the workshop, and that a technician will phone me within the next few days. On the 12th of March I phoned again the gentleman who took my call neglected to give his name, but assured me that repairs was being done, he could not say what exactly was the matter but that someone will phone me back before the end of the week. Needless to say that today, the 26th of March 2018 I still have not heard from them. I have phoned 4x today already, but it seems no one wants to answer a telephone today.
