A2 core headset

On the 05/07/20 I went to Chris hani foschini to purchase 2 phones.I was assisted by the lady working at cosmetics section I told her that I want a dual sim phone ,she then showed me a Hisense phone, unfortunately they were out of stock only display was left. I saw Samsung A2 Core on the display and I requested it.She went to collect the phone at the back and in my mind i thought she still recalls that I said I need a dual sim phone, I also decided to buy Mobice handset . When i got to the tills I was assisted by Nelly , I asked her if the phone was simlocked or not she said it's not as it is a dual sim phone. To my disappointment when I get home I realized that the phone is not dual and it's sim locked, I was misled.I went to Goldenwalk foschini they told me they cant exchange the phone for me I should go back where I bought it. On the 08/07/20 I went back to Chris Hani store, I got there at 08:55 am,at around 09h16 the store was still not opened. I tried to call their landline number to enquire what time their store is opening, but the phone went unanswered. I waited patiently until they finally opened at 09h26. I explained my dilemma, the the cashier called their assistant manager Thelma Gumatwa who carelessly told me that she can't assist me with the exchange since the store leader wasn't present and I should come back when she is around. To my dismay she couldn't even confirm when is that. I'm very much disappointed and disgusted with the treatment i received, the service was very poor and distasteful.If that's how they treat their customers they should just shut their doors because they act like they are doing their customers a any favors.
