Williams and his associated business entities contain numerous claims of fraudulent charges and dishonest billing practices, such as charging customers more than the agreed upon value or failing to issue refunds, as of 2015.

Dr. David G. Williams, along with his companies Life Fit Labs and Colon Cleanse Pro, have numerous poor reviews and claims of scams on sites such as ComplaintsBoard.com, RipoffReport.com and BBB.org, many of which cite an inconsistency between the advertised cost of products and services and the actual amount charged to customers. For example, one customer claims she made a purchase with the company for $4.95, which included repeating charges for more quantities of the product. She experienced significant delays in shipping on the product and once it arrived, she contacted the company to request a cancellation. However, the company proceeded to charge her $69.98 after providing confirmation of the subscription cancellation.
Other sites contain similar complaints regarding the doctor and his companies charging customers higher prices than what appears in initial contracts as well as failing to fully cancel service subscriptions after contacting the company's customer support department. The Better Business Bureau also views the doctor's companies in poor standing due to these billing claims.
