3rd post for the samsung S6 support

After getting the worst response ever, I am still waiting to be called. I have tried calling the Roodepoort service centre a couple of times and get no answer, I also emailed them and still no response. Does that service centre still exist. Does Samsung always treat there customers this way? Can someone please tell me what the hell is going on? I am truly disgusted by the service provided by such a large company.
