Appalled by lack of customer service

I took my Samsung watch in for repairs on the 3rd of November at the Sandton City branch. Two weeks later, no one can tell me turnaround time or give me any clear direction on the progress of the repair. I’ve tried calling the shop to no answer, went there this morning only for the sales rep to tell me to give him this week to find out what’s happening. I am so fed up with such poor customer service after I spent my hard earn money buying the watch at their store.
