Harassment

I went to Dis-chem yesterday to go purchase Centrum and some baby stuff i have been a Dis-chem client and i purchase most of my medication there. When i went out of the door i got stopped by a guy named Simphiwe asking me what did i do with the item that was in my hand cause he saw that i didn't pay for it . At that moment i was so shocked i couldn't even express my self i showed it to him and the slip than i left. I feel so heartbroken i got at work and told my boss about it I'm very disappoint in them and im never buying anything from them anymore
