Arrogant and Rude Service from Sandton City

I've got an S7 Edge that needs a screen repair. Before visiting a Samsung branch to get it done, I called the customer care centre first to verify what would be required from me in order to proceed with the repair. The call centre agent told me that I could go into ANY branch with my Proof of Purchase OR Contract.<br> <br> On Friday 1 April 2016 I went to the Fourways Mall branch, only to be told that they don't do repairs referred me to the branch at Nicolway. I had no time to go there.<br> <br> Yesterday, Thursday 14 April 2016, I went to the Sandton City branch as I was at the mall, only to be served by a very rude and arrogant consultant who told me very discourteously and impatiently that he only accepts a proof of purchase, nothing else. I tried to explain that the call centre had advised me that a contract is also fine, but his response was \well I'm the guy who's gonna fix your phone and I'm telling you that you must bring a proof of purchase otherwise you're gonna come here next time and I will still chase you away and tell you to bing a proof of purchase.\"<br> <br> It was completely unnecessary."
