Service & Delivery People
Use only reputable businesses for service and repairs. Check their references with the Better Business Bureau or get recommendations from friends who have had satisfactory service.
Whenever possible, arrange for service and deliveries by appointment. Never leave keys hidden for them or allow them inside your house when you are not home.
Ask for and verify identification if they are not wearing a uniform you recognize. If the person is unkempt, rude or menacing, you do not have to let him in. Call the company and request other personnel be sent.
Do not leave service or delivery personnel unattended while they are inside your house. Put valuables away from view and don't be drawn into conversations regarding your possessions or financial situation.
