Terrible service

On Saturday, 17 Feb we went to your Forest Hill branch. The queue was very long, for at 10am only 2 tills were open. After paying I realised that they charged me R10.99 for the carrots that was marked R7.99. There was no customer care counter so I complaint to a guy sitting in an enclosure. He just handed the till slip to the guy next to him, who handed it to the lady at the kiosk. There was a long line at her as she had to run the lotto machine and the people wanting to pay there, because of the long queue at the tills. She just put our till slip to a side and continued to help the people in the line. I told my husband to get into the line while I stood where I could watch her. It was a good thing, because at a point she crumpled our till slip with some other papers and threw it in the bin. I made her take it out again. When my husband reached the front another lady arrived at the kiosk and she handed the till slip to her. While she was still settling in I offered to go and fetch the bar code so long. She then rung up the carrots as R3 (???) and gave me R8 back. According to me I should have got R9 back, but I realise she haven’t got a clue how it works and we just left. Fortunately this is not our regular mall and I can avoid this Pick n Pay in future.
