A T-Mobile employee decided that the best way to deal with a complaining customer -- was to stab him. The 59-year-old customer went to a store outside of Philadelphia this week to complain about being double-billed, but according to the Philadelphia Inquirer, received a knife in the rib cage instead of a refund.

"Apparently he was double-billed. During the course of the verbal exchange, it becomes heated," a police officer tells the local ABC affiliate. "As the victim is going out of the store after the altercation, you can see store clerk stab him in the side."

In a statement, a T-Mobile spokesman insisted that the company was "shocked and saddened" to hear about the incident. It remains unclear whether or not the customer got his refund.
