Frequently Asked Questions

PissedConsumer collects contact information primarily from official companies' channels, such as corporate websites and verified social media pages. Data from these sources is usually added without additional individual verification. If the contact comes from a secondary source, the PissedConsumer team verifies it against fraud and abuse reporting databases and conducts additional validation, including test calls, prior to publication. We also perform regular, selective spot checks and respond promptly to users' reports and requests to ensure the data is current, accurate, and secure.

Phone numbers published on the official company website or its verified social media pages are considered authoritative at the time of the information collection. For contacts obtained from secondary sources, the PissedConsumer team conducts risk screening and additional validation before publication. We also promptly verify any phone numbers reported by the community and remove records that fail to pass verification or update their status.
Contact information posted by users in comments and reviews is not verified by PissedConsumer and may be unreliable. We suggest relying primarily on the official contact details in the company profile and reporting any suspicious content through the reporting form for your safety. Also, note that the phone numbers shown in the ads are not associated with the company's official contact details.

The PissedConsumer team always maintains the accuracy of contact details and reverifies phone numbers and email addresses of the companies. We prioritize reverifying data reported by our users and data that shows warning signs. Besides, we quickly check phone numbers that seem disconnected, reassigned, or compromised. Our team also promptly updates and cross-checks data when verified company representatives report discrepancies in contact details. However, please note that we do not guarantee fixed intervals for revalidating every listing.

The primary sources for the contact information listed here are official company sources, such as their corporate website and verified social media profiles. The PissedConsumer team also uses direct data from the company or its authorized representatives when possible.

PissedConsumer does not publish unverified contact information. We mainly rely on official company websites and their verified social media pages. They are regarded as authoritative sources. Our team cross-checks every update and conducts thorough risk screening. Whenever possible, we use contact details that companies or their official representatives give us. If so, everything stays current. If customers or businesses report incorrect contact information, we start a validation process and cross-reference the details with trusted third-party sources.

Names, phone numbers, and email addresses listed on this page are provided for informational purposes and to help you contact the company.
