Worst customer service

I went to Mr Price in Irene Village Mall on Saturday the 10th July 2021 & there were not a lot customers, but the was only 1 cashier who took long to assist 1 customer. I was patient even when they attended to someone who came after me & queued at the wrong place. I had taken 2 toddler items that were marked down (I even have pictures of the prices that were on the items) but the cashier gave me a lame excuse when the prices were different when scanned. Then both cashiers kept me waiting again when mine couldn't take cash. I asked questions but they both stared at me with no answers. Those people always drag their legs & even speak however they like around customers. This wasn't the 1st time I threw in the towel there & took my money
