&gt; So yeah, you can fire the customer<p>You absolutely cannot ban a customer from your service 99.9% of the time as front-level support. You often can&#x27;t even put the phone down except in certain pre-defined situations which are decided on without actually communicating with front-line support, never mind groups which might have specific issues within your front-line support team. Harassment is expected and you&#x27;re expected to deal with it, whether gender-based or not. The best you can do is try to deflect them, as you say, and let them do exactly the same thing next time.<p>If there were actually consequences to harassing people, few would do it - but as it is, in many cases, from small companies to large ones, retaining the customer is more important than your employees.
