Accidental $5,000 Tip Leads to Eight-Month Banking Nightmare

A California woman accidentally tipped $5,000 at a San Bruno store due to a faulty payment terminal. Linda Mathiesen, a special education teacher and single mother, recounted how she tried to correct the error but the clerk couldn't void the transaction. Mathiesen then contacted Wells Fargo, her bank, repeatedly over eight months, but received no response. "I called them 22 times," she stated. After sharing her story on social media and with Univision, Wells Fargo finally contacted her, agreeing to a full refund, including interest. This highlights the importance of consumer awareness and prompt bank response to errors.
