Terrible Service at PicknPay Cosmo Mall

I bought a blender today at PicknPay Cosmo Mall,When i got home,My mom didnt like it and asked me to exchange it for an iron.I went back to PicknPay Cosmo mall the very same day to exchange the blender,i got assisted by a guy named Pedant,who's apparently the manager of the store. He told me that he cant exchange the blender because the blender is not faulty nor broken and i asked him about their exchange policy regarding electronics or terms and conditions but he didnt bother to explain nor is it even written anywhere on the receipt. I asked to speak to his superior since i was not getting any assistance from him but he rep**** with arrogance and mean attitude and said he's the only person that can assist me today. His attitude and incompetence got the best of me, i then lushed out, he rep**** by saying 'because of my attitude he will not assist me'. I told him that I'll make sure that the matter gets reported to his superiors. He arrogantly told me that i should do as i please. I left the store and wasted more of my time and money and went to PicknPay Northgate to exchange the blender that i bought at PicknPay Cosmo. To my surprise, the blender was exchanged at PicknPay Northgate without any trouble.
