Most people whose call to a business goes unanswered never call back; a widely-cited industry figure puts it as high as 85%, who instead try a competitor.

The specific 85% figure is repeated across the call-handling industry but has no locatable primary study (it is attributed inconsistently), so treat it as a directional industry estimate. The underlying behavior it describes, that an unanswered caller usually moves on rather than retrying, is well established.

This figure is load-bearing across 23 pages on SalonAI. See where, below.
