Avoid altering the product merely to produce stronger evidence. Check that the proposed resolution addresses the problem you actually reported.

What should I check when current terms differ from my saved order information?

Identify the exact wording that differs between the two records. Resolve the factual difference using dated records and clear communication rather than assumptions about which page prevails.

What should I confirm before purchasing on behalf of an organization?

Do not assume an ordinary buyer account automatically represents an organization. Clarify who should receive product information and order updates.
