That is superb. What you're really saying is that 80% of your customers no longer feel the need to phone you.

"What you're really saying is that 80% of your customers no longer feel the need to phone you."

No, they're saying call volume went down by 80%. We know nothing about how many callers generated the calls before and after. Maybe each and every customer used to call them 5 times per month, and now each customer calls them only once per month. That would be an 80% reduction in calls, but a 0% reduction in # customers who feel the need to call.
