Diamond Certified’s rigorous 12-step company certification process is the most reliable anywhere. They survey a large random sample of only REAL customers by telephone to get the most accurate rating and verify only actual customers are responding. By surveying from a company’s entire customer base, they ensure the results of their study, good or bad, truly represent the company’s our customer satisfaction level.
Companies must score Highest in Quality in customer satisfaction (a 90+ on a 100 scale) and pass all of our credential-based ratings to earn Diamond Certified. By requiring such a high score to qualify, they cut out mediocre and poorly performing companies. They then conduct ongoing research and ratings to ensure all companies maintain their high performances.
