Threatened by game employee

Hi. This is Siphokazi . I bought a heater at Game store (promenade branch) on the 30th of April.. It was stated on the box that the heater comes with a humidifier and a fan.. I got home switched the heater on and loved it.. On the manual the was no explanation as to how to operate the heater. On the heater there was a humidifier and a fan button and other buttons as well.. I tried to switch the fan button on however there was nothing happening. I even googled just to find out how the heater work but with no luck.. I went back to the store this morning just to find out if the heater was faulty or I was operating it the wrong way.. The cashier at Customer service called a guy named Bonke to assist. I explained the situation to the guy for some reasons he got defensive and told me they have been selling the heater for years and no one ever complained about it. I tried to explain to the guy that I’m not complaining I just want to find out how does the fan works. Bonke did not listen and got to a point that I must be given my money back which was not even the request from the onset as I loved the heater. I asked the guy how the fan works and he told me that it cools the heater inside . Cashier gave my money back and requested that I go and fetch the money at any of the till and that was Bonke’s requested not mine. I decided to obliged and left the store. I went back to the store and approached someone different. The guy who assisted me advised that he does not know how the heater works but would call and find out from some else who works with the heater. He explained to me and that was something different from what Bonke guy said.. I took the heater again as I was on my way to pay I came across Bonke and I called him to tell him to tell him I was not happy with the way he spoke to however I did not even get a chance to finish. Bonke told me what was said in customer service ends there. I told him he is still at work even thought we were not at customer service. Bonke told me not to point my fingers at him of which was not even the case and that if I want to get personal and I should take his number and call him and promised me that I’d regret. I asked if if he is threatening me however he kept on telling I should take his number.. with all this gender based violence happening I walked away as his statement gave me so many ideas . I know that in some cases customer are rude however I went there for help and all I got after all was a threat as if I was someone who went there to fight. The way I am so traumatised right now I dout I will ever set my foot at the store. It even took a lot in me to write this as I’m having all these idea about what he will do it he finds out I have laid a complaint against him..
