Shocking service

We were sold a faulty laptop from the Benmore Pick n Pay. We decided to take it back to Hyper Woodmead as they have a bigger range of computers. I was the told by Honey Bee and Kenny (the store manager) that they could not exchange it for a working unit. I was also told that if I wanted to have it replaced I need to go back to benmore, where they don’t have stock. I was then told Benmore can IBT one. Which will take days to sort out and my daughter starts school on Monday. This is completely unacceptable as they are both corporate stores.
