Bad experience at Guess Store in Lochlogan Bloemfontein

I purchased items at Guess Store in bloemfontein Lochlogan on the 21 May 2024. To my surprise my slip and and the items purchased were communicated to the next person.The said person also called the store to verify the purchased items and the consultant gave out the details of what I have bought together with the card slip ..my privacy was compromised by that store..
