INCORRECTLY CHARGED FOR PROMOTION ITEMS STATED ON PROMOTION BOARD

Last week on the 01st of April 2021 at about 9;30 I went into the Foschini store. It was then I noticed that they had a promotion on pajamas for 2 sets for R299-00. So I proceeded to the cashier after waiting while the 3 cashiers were chatting not interested or even acknowledging me I asked would I beable to purchase them without my card because I had my Identity Document. They advised No I need my card however I can make one downstairs I said no I will come back. I still queried how long will the promotion be until they advised they were not sure. I left the store excited because for me this was a great special that I can purchase for Mother's day gifts. On the 6th April 2021, I then re-visited the store to purchase having my store card after selecting the items I proceeded to the cashier and asked again how long will this promotion be until she again advised me she does not know. While she was processing my items she advised she cannot find the promotion code as they have so many promotions happening. It was then she realized the promotion card "was apparently placed on the incorrect items" I asked her to call the manager as I have already spent so much time in the store and the promotion card says two items for R299-00 plus the consultants on the 02nd April confirmed the very same thing. Lungi the Manager came through looked on the floor and advised the promotion card was in the incorrect place. I advised her that is not my problem and also prior to this the cashiers/consultants already advised me and confirmed. She then acknowledged and advised me she would give me the items for R299-00 as STATED ON THE PROMOTION BOARD. she still took down my details and promised to view the cameras for that they because they have to take this matter further. Today is the 07th April 2021 I noticed my account was charged R600-00 so I proceeded to call the store and query this. Lungi is not in today. So I spoke to Laiken as this matter cannot be delayed. I would never pay R600-00 for pyjamas online there are numerous specials for R199-00 for a full set as well as in-store. She was not at all helpful. All she advised me was that she will contact Lungi which she did and came back and told me Lungi did the correct thing?? Really So Lungi advised me R299-00 for matching sets as the promotion states today I am charged R600-00 if you look at my online shopping I only purchase on promotion and reasonable prices. I would never pay R600-00 for pyjamas I need this matter sorted because what the customer sees she pays and also your consultants confirmed it and lastly even Lungi advised she would give me the items for R299-00 as stated. Today she's not in and now I must just settle with been ****** because the staff members have no interest in knowing what is going on in the store??? They don't even acknowledge clients and that is why they give incorrect information. It is totally unexpected. I have absolutely no desire to keep pyjamas that cost R600-00. Laiken if she is in Manager she needs a lot of training for her customer service. Her tone of voice and leaving a customer unhappy is clear she should not be in that position.
