What happens next

A complaint moves through statuses: received, sent to operator, then resolved, unresolved or rejected. The operator has a fixed window to answer; on silence it is extended once, after which the complaint closes with the verdict «operator did not respond».

That verdict is surfaced in the brand row in the top listing as a warning, and two such complaints in a quarter cost the brand its place in the recommended lists. Disputed amounts enter the safety score not as a count but as a sum divided by a proxy for operator size.

What is not a complaint

An opinion about the quality of the line, unhappiness about losing, a claim with no amount and no correspondence. For that there are reviews with aspect tags on the brand card.
