Unacceptable

MR PRICE BLUE ROUTE MALL.Bought a cellphone Monday 26.2.18, returned it to the store 28.2.18 but the cellphone lady left at 6, the store closes at 7, how pathetic not to have a reliever, I was then told to go back the next day because she would be in, I went all the way back only to find that she was off, I spoke to shaun, who told me I cannot exchange the phone because the phone needs to be taken away to be checked, I bought a hisense 962 something, the phone itself is slow, network+wifi is slow, the battery doesn't even last long even though the phone wasn't used, chatting , music etc, my memory card that worked in my previous hisense phone doesnt even work in this one, so why should I pay for something im not satisfied with??? I paid 999 for the phone and I am willing to pay the difference for a better phone or I will take this further!
