Reliability Report Search
The Better Business Bureau (BBB) evaluates companies to ensure that they have "sound advertising, selling and customer services practices." If a company has sought and been granted voluntary accreditation with the BBB, you know that they meet BBB standards and have made a commitment to make a good faith effort to resolve customer disputes. Even if a company has not sought BBB accreditation, the BBB may still provide a reliability rating that organization.
