I bought a MacBook Pro 16 inch from the Istore preowned on 30 March 2026. It arrived the next day. I bought it for my daughter who was writing tests at the time and she opened box on 10 April and it was not switching on so she powered it and still did not work. I bought another one and sent back for a refund. The macbook was taken for inspection and they said a liquid spilled on it and it was recent. I don’t understand as we did not spill anything on the macbook as we returned it how it was received. We received a dus and even when you buy a used item at cash converters they switch it on to show the customer that it was working. I did not receive such a report from istore as to when the macbook was switched on and the date before shipping to me. I am highly disappointed in their process and I spent R12 999.00 on a dud and the istore expects me as the customer to forfeit my money due to their incompetence. I am sure that they should really have a look at this and remedy the situation
