Reason	Items	Amount
More billed than recorded that day	19	$17
Disputed	19	$17

3What the money bought

Your records' sessions for the period, by what happened next. "Came back" means the same person opened a ticket about the same type of issue within 7 days.

Outcome	Sessions	Share
Resolved, and the person did not come back	540	62.9%
Resolved, but the person came back	97	11.3%
Handed to a person	129	15.0%
Abandoned or unanswered	92	10.7%

Per-session pricing charges for these whatever happened. They are not billing errors; they are why the cost of each resolution that held is higher than the price of one session.
