Useless Manager, Terrible service

Yesterday I went to the Boardmans in Maerua mall for the second time, after being told that if I came back on Monday they would have stock of the item I was looking for. They did not. The sales assistant informed me that they might have stock right then but she didnt know because it was all still packed into boxes, so I asked her when would she be able to tell me when they would DEFINITELY be receiving stock, she told me she couldn't. By this point I was furious, because this was my second trip to Boardmans already. I asked to see the manager, his name was Josephat! My initial impression of him was pure annoyance because his appearance was so scruffy that I already knew what kind of response I would receive from him, I asked him when they could let me know about stock of the item I was looking for, he told me the same as what the sale assistant did, he doesn't know. So i asked him how can they run a store without knowing when they will receive stock of something or having boxes and simply not bothering to unpack them to find out??? He very rudely said 'Listen, I told you we don't have!' and turned his back on me and continued chatting to the young girl behind the perfume counter!
