(WPTV-TV) 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.
