The answer
Ask for the decision, policy language, facts relied on, missing information, scope and calculation in writing. Keep a complaint file and chronology; compare the observed damage, qualified cause findings, estimates, depreciation, deductible, limits and exclusions. Escalate through the adjuster, supervisor and insurer complaint liaison as appropriate. Alberta also identifies ombudservice, statutory loss-amount dispute and legal pathways, which have different scope.
Calgary-specific context
A dispute about the amount of loss is not the same as a dispute about whether the policy provides coverage.
What to do next
Define the exact disagreement and requested resolution before choosing the next escalation path.
Verify before relying
