Customer service. Scenario 3 of 6. Abuse and limits
When it turns personal
A caller is angry about a late delivery. You apologise and start checking the order. He begins swearing at you, calls you useless and makes a comment about your accent.
Your company has a policy on abusive calls: one warning, then you may end the call.
The principle
Anger about a problem is part of the job. Abuse aimed at you is not. Give one calm warning, follow your employer's policy, and record what happened.
