Unfortunately, there isn’t a comprehensive resource that gives information about the reliability or reputation of a company. However, there are a couple of places you can go to see if consumers have filed complaints against a business.
Missouri Secretary of State
Search for individual companies that have had complaints made against them, see the number of complaints and whether or not the consumer and company were able to reach a resolution. Database includes companies outside of Missouri.
Greater Kansas City Better Business Bureau
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.
