I went to Pick n Pay at Boulders Mall today after work, I bought a shirt socks and a few food items, I get to the till my bill is almost a R1000 I am a bit skeptical but then I thought things are expensive now and I did not even look at my till slip. I get home I just happen to have a look at the slip I did not want to throw it away because I did not fit the shirt properly because the fitting room was closed in case it did not fit me then I can return it, to my surprised I was charged twice for one shirt, I was so so so disappointed now I am not sure if this was done on purpose or it was a mistake but something tells me it was on purpose. Pick n Pay am so so so disappointed at this level of dishonesty from your cashier.
