Customer service/ Pricing

On the 1st December 2017, I went to Game Store in Menlyn, I took Baby Floor Seat it had a price on top of it saying ON PROMOTION R179 the tag arrow looked down on the shelf that had a Baby Floor Seat, there were no other price below, I took it and went to the cashier, which it turned out to be another price, I told the cashier what I saw we both went to the shelf and she told me it's the price for something else and I asked her how should I know because there is no other price other than that one, she could not answer me, her name is Lucia, She called her supervisor, she said she cannot authorize the purchase because its a lot of diffence to the amount I saw, she called the lady who works on that department, she came and speak her language with an attitude saying that price I saw it's for another thing when I tried to speak to her she never even listen to me she just turn her back and went to where she from, the supervisor called her manager his name is Andrew Maeko who also told me the same thing that the price itsfor something else and thats how they price their things, my Question still stands where is the price for the item I want no answer, I took him and show him the other similar promotions that were done differently to the one I want he couldn't explain to me, then he said he cannot give me on that price I saw. I ask for the store manager his name is Shaun Perumal who also refused to give me the item with price I saw, instead he offered me the last promotion of the Baby Floor Seat, I ask him if I am wrong why is he offering me the price that it's not the, he said that a lot of money that he will loose, the Question is why they put wrong price and if it's for other item where is the price for the one I want and why the arrow on Promotion Tag is looking down to the Baby Floor Seat, no answer. I left the shop I phoned the customer service line which I spoke to Rina who took my details and said The store manager will phone me, I never got a call the whole weekend, then Monday the 4th December 2017 I called doing a follow-up which I did not get Rina, the lady who answered the refered me to call ********** 600 to take this matter up with Tinus Geldenhuys, which he was not there I was refered to speak to Elizma who told me now they cannot give me with the price I saw. Then feel minutes after I spoke to her I got a call from Shaun still offering me the same offer of giving me the price of the last promotion for the Baby Floor Seat, I just said ok even though I knew I am not happy. Game Store Menlyn it's one of the big retail stores for them to treat customers like that, I don't understand why they not admitting that they are wrong for not putting price on the item and acknowledge their wrong. I am also disappointed with their customers services where the is no follow-up on complaint that a customer logged, I wonder how many negligence that Game Store Menlyn does and not being attended when a customer is complaining? I am very disappointed customer. Pumza Tokota ********** 813
