Poor service

I am extremely dissapointed in the service i received today. I went to your parow park store and bought Rama which showed on the special sticker on the shelve, 2XR50. When i got to the counter, the price did not go off and the teller called the supervisor Primrose, she than sent one of the new packers to where i pointed the sticker and the butter was. The guy came back and said the manager there said it was the previous weeks sale. I informed him that its not my problem if its an old sticker, i pay what i see. Primrose than requested the Supervisor for the Dairy section to come to where i was, after almost 20 minutes this Supervisor who was so unproffesional, come and had a very bad attitude, while the teller was explaining,He asked what should he do and walked away. 5min later he came back as Primrose told him i was still there, I told him to go and look at the camera footage, cause i know i saw the Rama butter which was 2 for R50. I told him it was a big-ish paper so he will see on the footage who removed it as im 100%sure that it was there. The Supervisor (Name: Search) came and said there is nothing on the camera which is a total lie. Not only was he extremely unproffesional letting me waited for a total of 45min, he was also dishonest in saying that the discount/promotion page was never there and not moved yet i was not the only 1 that saw the page was infront of the Rama which said 2 for R50. If this is not resolved, i will take this further to FASA, NCC and ICASA Ombudsmans.
