Refund

My name is Khululwa Mfondini, I bought tablet iLife 7inch on the 25th November 2020 and the problem with the tablet was freezing, takes more than 10mins to start so I tried to call them in December no answer. I brought the tablet back in the store which is in Menlyn on the 15/01/2021. I was assisted by a guy called Victory who told me to wait for 14 working days. I went there on the 5th of February to know what is happening about the tablet and Victory told me to come back Wednesday the tablet is with the Technician so its going to be on the store by Wednesday. He promised to give me feedback after till now. I even spoke to the Manager which is Joseph they promised me that they will do the PCA claim on that day. Today I called again asking for Victory he is OFF and the person who is assisting me is Lennox told me that on the system it shows that the tablet is not yet back to the store which means I must wait for Victory to come to work tomorrow. My problem is that I told them I'm no longer interested in the tablet I want my money back and they don't even communicate with me they keep on promising to call me back which they are not. It's almost a month now waiting for them to refund me my money while they are telling me different stories about the tablet. Please assist me I want my money back.
