put **** special sign then call customer a ****, worse company in South Africa ever

I want to Food *****s Market woodlands pretoria store on 2020/12/29 4:00 in the afternoon, I bought 6 packs of unpitted prunes and other things. The unpitted prunes was place right at the entry with sign says 2 for R54.99. But when we went to pay, The unpitted prunes was not 2 for R54.99, was 1 for R54.99. So I told the cashier about the sgin for special, she start to speak in her own langue with other cashier and laugh. like she is saying I am trying to con the store, so I can get a cheaper price, so I ask her for the manager, the manager came and the same thing happen, the manager basically called me a ****. I had same issue with this store many times before , they has the wrong price on the item, I mean if you has the special day before, your sign for the spical should be taken off before you open the stroe to the customer, I mean it was already 4 in the afternoon, you still have the old special sign, and when customer tell you about it, you call him a ****. So i let all the items and walk out of the store. I was not trying to let them sell me the items at the lower price, the manager could just say sorry , we forgot to take the speical sign off, instead calling thier customer a **** and speak in some language your customer dont understand and laught at them. I will never buy anything from Food *****. I will tell all my friends about it. you the worse company in South Africa.
