False adverti*****t

I went window shopping for a cellphone to the Eastgate mall and found a stall for Xiaomi. The lady convinced me I would get a free watch if I purchased their pro version (R6k later). So I did (Hifi Corp), after the purchase I went to get the watch and was advised there's no stock, I should come on Thursday. I went back on Thursday and their stall manager was there advising they don't have stock. I advised him the only reason I purchased the phone was because i'd get a watch with it. Anyway he didn't care, I now understand why the big mobile companies do not stock your products. It's because of your false adverti*****t and lack of customer service.
