Selling and buying not working according to me

<p>So I sold My Xperia M4 Aqua at Secunda to buy a smaller phone. I sold my phone with original charger and USB cable. I went around the corner to the buying counterto get a smaller phone. The phone that I wanted had a generic charger with a generic cable.</p> <p>The buying counter wouldn't accept my phone without the original charger, but the selling counter wanted to sell me a phone that had no original charger. How does that work? The phone I wanted to buy didnt want to charge or switch on at first. Explanation given was that the buying counter accepted the phone without the original charger.</p> <p>I also wanted to sell my laptop. The signs in the buying counter said that all laptops from R1000 to R5000 will be accepted, but I was offered a rediculous amount for my middle range laptop. I wanted R6000, prepared to go down to R5000 for my R9000 laptop. I was told " customers do not want to buy laptops like mine because they don't know the difference". How does that work?</p> <p> </p> <p>Reply would be nice.</p> <p>have a good day</p>
