(WXYZ) - It was a shouting match serious enough for a clerk at a Detroit cell phone store to start filming the exchange.
The heated argument was regarding a woman's son, who bought a cell phone more than two weeks ago and wanted a refund.
"They came in a week ago, I explained them the situation," said the store clerk, who wanted his identity hidden. "I showed them everything on the receipt."
The clerk who shot the footage says after trying to explain to the irate mother her son's date of purchase exceeded the store's 7-day policy for refunds, the mother wasn't taking no for an answer.
"Take everyone's [expletive] money!" said the mother caught on camera, "Take it!"
In addition to knocking down signs, the clerk says she even used a knife to damage display cases. Things took a strange turn as the customer addressed the clerk's camera.
"Take my picture. Take that!" said the woman, as she lifted her dress and mooned the clerk's cell phone camera, "Take that! You got that? Because I will be back. You got that close up? Cheese!"
"I want you to know there's a reason why I had to do that," said Stephanie, the woman caught on camera. "He's telling me my money is up in the air, I can't get a refund or another phone."
Stephanie says the cell phone store sold her son an outdated, damaged phone.
"[The store] needs to either give me another phone or return my money." said Stephanie.
"There is no excuse for anyone to walk into anyone's business and do that." said the clerk, who says the store plans to pursue charges against the customer.
