Bad customer service and lack of knowledge on own promos

Good day,

My name is Siyabonga Mhlongo (Clubcard number: ***) on the 26th of March I went to the Clicks Baby store at Mall of Africa (receipt number S01816 #8938) - thank you to the floor ladies for assisting me in store but all that was down the drain when I got to the till, the gentleman (Abongile Mariana) and his colleague were not helpful and I think the store and management needs to invest more time in training the staff when it comes to promos and how to handle customers asking questions. The 3 for 2 promo advertised did not apply, I explained to him that the lady on the floor said it would - this was even after he made me pay only then he and the other gentleman say no I should’ve asked them at the till and that we should wait for a credit. I was literally the only customer in the store the least they could’ve done was to clarify this before making me pay - also the attitude in which you deal with customers is not right I mean for being the only customer at the store to feel like I’m bothering them is not right and not inline with the values of your store - you guys need to do better man
