What if a major store placed a "bolo" on a customer? Is this legal and how can one be removed from this "list"?.

A major store has placed a bolo on a customer and this bolo is unjustified. How can someone go about getting removed from this "bolo list"? (Bolo: be on the lookout) No theft had ever occurred and no one has ever asked the customer to leave any store. Yet, the store has placed a sort of a "red mark" on this customer. Every time the customer enters one of their stores, within five minutes, the front desk people start calling various people on the loudspeaker. This doesn't stop until the customer has left the store. Paranoia? No. This happens every single time and always within five minutes of shopping. This has been going on for a couple of years now. It happens too frequently to be a coincidence. The customer care office was contacted and, subsequently, the customer received a call from the district manager. Explained the situation to the manager. The manager says no such thing exist.
