The BoostMyScore Money-Back Guarantee:

BoostMyScore guarantees that the tradeline(s) you lease from us will appear on at least one of your three credit reports in less than 60 days from the First Estimated Monthly Reporting Date for each card you are added to as an Authorized User. If the Card does not appear within 60 days of the First Estimated Monthly Reporting Date, BoostMyScore will provide you with a full refund of the money you paid for the card you purchased.

This guarantee is limited only to the tradeline posting to your credit report within the promised time frame. We cannot and do not imply that you will receive any specific point increase in your credit score, nor do we guarantee that you will be approved by any lender for a loan, as those decisions are entirely up to the lender and is something we have no control over.
