Clicks are becoming ****mers on their promotions!!

Im very disappointed with Clicks store in Blueberry Square. They trick their loyal customers into buying things that they dont want. I ran into a 3 for 2 special today which stipulated that :Clicks smart lunch boxes ,water bottles and lunch bags cheapest one is free. When i took my 3 Smartlife products which were lunch bag and 2 lunchboxes I was told that the system doesnt recognize the special. Then Kennedy Hlongwane told me that I have to take 3 of the same items? I then queried that how is it the cheapest free when im told i can only take same items with same price? Kennedy then agreed with me that he sees what I see but the system is not taking it. I then opted (reluctantly) for 3 lunchboxes that were still rejected by the system. Then a supervisor #11 as stated on my till slip then manually made the deduction. when I asked why cant they manually deduct from the 3 products that I initially wanted i was told that it cant be done. Is this then not lies from the store? now i was forced to take 2 items that i didnt want because they want to choose what to manually deduct. you are ******!!! sies man
