Unfairly treated

This is complaint on how unfairly I was treated by the female security guard at de Villiers branch because im using laptop bag as a hand bag….and yet the store rules says no bags are allowed, but as I was standing by the door I could see people going in and out of the store with the lunch bags and huge huge bags but I was not allowed to enter with my bag . I tried explaining that im using this bag as my hand bag , I cant enter the store with my fone and purse on my hand what if someone snatches the purse on my hand while im in the store , she told me its not her problem. I asked for a manager and she refused calling the manager ….and she instructed the cashier not serve me . That’s a total disrespect , it was in the morning , I was on my way to work. She doesn’t respect me as customer and my time and that is not fair because all customers should be treated equeally . Just because I am Sangoma doesn’t mean I deserve little respect .
