Very bad service

I went to Samsung because of a problem with my Whatts App application. I had to wait an hour before I was helped. This was 15h58 in the afternoon and they were not busy. I was customer number 24. I eventually got helped by a guy named Lebo. He didn't communicate properly, I just heard something about update, to realise later it is a software update. I asked him questions about the other problems I am experiencing and was told it will go away. I walked out of there not a happy person. I have lodged a complain to the Constantia office the following day, did receive an e-mail they will get back to me but till date haven't received any other feedback. Is this the way that Samsung treat their customers? Just because I have A S4 Mini and not a Galaxy or S6 phone I can get treated like this?? <div><br></div><div><em>(Report edited by hellopeter.com)</em></div>
