defective product/service complaint

today on the 24th of December 2017,I went to sportscene king williams town,with a sneaker that was purchased for my birthday which I have 2months now,when I walked into the store I stood in the line to speak to a sales consultant and in front of me stood a old african lady and her grandson ,which she bought a size 4 sneaker for and wanted to exchange it as she wanted him to wear it for Christmas and the consultant told the lady his of line,she then ask if there is no solution and the sales consultant told the lady that it is not his problem that they offline.so after seeing that I hoped that my complaint would be abit better and to be honest it wasn't .I was assisted by the manager in store that told me she had to wait for a decision from the area manager and I said to her that I am going to east london if he is there at one of the stores ,I can take it to him as I am going there ,she then called him and he said he is on his way to the store and she told me I could wait and speak to him myself,to find a solution.I then left the store and returned after a hour and she called him to ask him where he was as I was waiting and he said he is on his way ,after waiting for about two hours I decided to ask for his cell no. and she refused to give it to me,I said it's fine and I called Hemingway sportscene and they gave me his no. I then called him on his cell as you can imagine I have been waiting for two hours and finally got to speak to him and all along he was in east london ,then I was very upset and felt like I've been liad to ,I then told the area manager that I've been wait to speak to him and his blaitent reply was he never told me to wait for him and why did I ,I then said because I would like to resolve it as I am going on holiday,I then told him I'm on my way to east london and I would bring it to him and he told he will be leaving I asked him to wait 25mins and he didn't seem interested to wait ,to help a client so I told him I will now be leaving the goods at king williams town sportscene and that this has now become a service issue ,he could not even apologise for the inconvenience caused by their communication s****s and neither did he wait in east london for me,25Mins and a little empathy would have been fine and I would have been fine but no,he had to be rude towards me ,and I called him and asked him if he would call back and he said he would and it is 6hours later and I've never been contacted.I work for a retail brand that believes their people make a difference and after receiving this type of service I can say that your people do make a difference and how we as consumers look at your brand.I will not be accepting and exchange ,I want to be credited for the goods and going forward I would like to take my business and my wife business else where .I would appreciate it if I could deal with someone else going forward as the area manager attitude towards clients sucks and I can't deal with people that treat me a certain way not in today world where we deserve better service.
