Pick'n Pay Delmas Bad service

I went to pick'n pay Delmas to buy Russel Hobbs Microwave and it cost R999 on the pamppamphlets but on the till it cost R1199.

I ask the cashier why the price differ and she called her supervisor. The supervisor came and saw it then she disappeared. When she came back after 25 minutes she said, she was looking for email saying this price is wrong. I said, why they don't take all this pamphlets and destroy and she look at with attitude after say" i cannot answer your questions but this price is wrong.

I feel like, they have been robbing us cz this is not human error and am buying my groceries and clothes etc from them and this is what they capable of doing. Am disappointed cz i trusted them
