What to send
Use the contact form or email info@estatecalchub.com with the affected URL, inputs or example numbers, the result you observed, and what you expected. For a source issue, include the claim and a link to the relevant official document. Do not include account credentials, private financial records or another person’s personal details in a report.
How we review
We first reproduce the displayed result and compare it with the formula, units and rounding on that page. For an editorial claim, we read the cited source in context, check its date and confirm whether the statement needs a qualification or change. If we confirm a material error, we update the affected page and its review date; related pages are checked where the same explanation is reused.
What a correction means
A reported disagreement can arise from a different convention or from an actual defect. We explain which applies when we can, and we correct demonstrated errors. The page’s current formula and review date are the public record of the published version. For a decision tied to a transaction, verify the actual documents and obtain the appropriate professional review.
