From the recent story - Square faces rancor from merchants over customer service:

"Barry said she grew so frustrated exchanging e-mails with customer service representatives that she drove two hours to the company's San Francisco headquarters to get some help in person.

Instead, she cooled her heels in the lobby for a couple of hours. No one would speak to her, she said, and the security guards threatened to call the police. Then Square deactivated her account, saying "high-risk activity was detected."
