Over charge at tills BE CAREFUL

On the 25th of July I went to your Carlswald store where I had great assistance in the supplement Isle from the gentleman in the supplement Isle as I was looking for an energy drink replacement with BCAA. his great work was overshadowed by the fact that when I got to the till the lady overcharged me for an extra 6pack of the USN BCAA Energy drink code *** instead o being charged for 2 6 packs to my surprise when I got home I realised she charged me for 3 cans when you do your stock take and realise you have an extra 6 pack on the floor it's because your tellers are overcharging us and *****ing our money this is not right from such a reputable brand
