Ackermans Atlantis - Rude staff!

on the 1st of June 2018 I visited Ackerman's Atlantis branch regarding their 3 for 2 on girl tops and track pants promotion. The adverti*****t is up on a 4 way rail and beautiful track tops and track pants are hanging there. I decided to purchase 2 sets. When I got the pay point I asked the cashier as no deduction of the 3rd item was deducted and she said no its R50.00. As I left the store I felt that this is not correct as I understood the adverti*****t, The floor assistant told me its not the items on the rail with the adverti*****t that is on promotion but the I must look at the picture on the adverti*****t and it is exactly that! I was obviously not impressed and asked to speak to the manager. The floor assistant now call the manager and the manager replies to say IM EATING! She then calls on the assistant manager at the cash desk about 2metres away from where she is standing explaining my concerns and the ladies reply to the floor assistant was "ha a it werkie soe nie" MY QUESTION! Who the hell does she think she is talking to? Humiliating me infront off other clientele! For their wrong doings! I then decided to leave the store and on my way out I had to stop another customer who was buying from that rail! I then took pictures and the floor assistant was asked to remove the items from the rail! How is CPA protecting us against Ackermans false adverti*****ts? How will the staff in that store be trained with customer service etiquette? Are you using cheap labour? Because that was the low level of integrity I experienced in that branch! I will definitely make my experience known to our community and I do have proof! The staff in that branch should appreciate that they have a job and can provide bread for their tables at home! they act as if they own Ackermans Atlantis with a vulgar and loud attitude! Personally as a successful business lady I will not spend my money at a store that cannot deliver service! this is disgustingly pathetic!
