Worst service ever at Steyn's stillbay

Went to Steyn's in stillbay and wanted to pots for flowers the price in the shelf stated with arrow up to these pots for R50.50. Get to the checkout counter to pay and the price was ridiculous more than what is advertised on the shelf... so I went and showed the lady and she inky said in a rude way well that's not the price your getting these pots for this price is wrong... where is your professional attitude lady your working with the public and a smile never killed anyone!!!! She stated that she will not give me the pots at 50.50 and that's that..!!!... Steyn's needs to know how rude their staff is and ensure that the correct priced are in the correct shelf..!!!!
