Worst customer services

On the 20th of October , i received one of the most horrifying service from a Assistant Manager who was on duty by the of Gerrit urged with me even I after he hard seen that he was wrong . I had bought an item which they had displayed that it was on promotion and when I got to the till it wasn't. I asked to speak to the manager and he came. As i was stating that they must be aware of false adverting he had already amused that I didn't want to pay. He went on explaining that the bar code had to match with the bar code of the item which is on sale . I went back to the shelf and I compared and I was right the item was supposed to on promotion . I called from where he was already discussing me with his colleague without him realizing that I was still around. I showed him and he saw that he was wrong and he didn't apology but instead he continued arguing with me in front of the staff and other customers. The last time I checked the Customer is always right and never urge with them . This was the waste experience i had . He even forgot to void one of the items and I was charged for 3 instead of two. Very disappointed. <br> .
