HOUSTON, Texas (KTRK) -- You may suspect your mail has been roughed up, but actually seeing it happen can be even more infuriating.One Houston postman was caught in the act of being less than careful with her deliveries."I was sitting here in the living room and I heard boxes drop hard," said Andrea Rosenbaum, who checked her surveillance video camera when she heard the sound."I was shocked and it made me mad," Rosenbaum expressed.She saw the mail carrier toss one, then another package onto the porch. And then she was gone.This time, nothing was broken. The items were plastic and they survived the throwing.But even though her packages were fine, Rosenbaum has a message for the postal worker."People pay money for them and just to be careful. Just think of it like if it were your package," she says.The US Postal Service issued the following statement:"A mishandled package is unacceptable and does not reflect the careful efforts of the thousands of professional, dedicated carriers in our workforce. We were disappointed to see the actions of the carrier in the video. We take the customer's concerns very seriously and apologize for any inconvenience. The Postal Service is researching the matter and will follow up to reaffirm existing guidelines governing how to correctly handle mail and packages. Customers with concerns about their mail service should contact their local Post Office or the USPS Customer Care Center at 1-800-ASK-USPS."
