"My experience was initially great until I had a medical emergency and had to cancel my account. I cancelled my account and was told that the following payment would still be drafted of $89. As of the date that I cancelled I was unable to access my account although I was being charged another $89. I would not recommend any company that does not have a fair cancellation policy. I cancelled my account with Equifax and was still able to access my account and was not charged any extra fees."
Here’s a good example of when a reputable credit repair service can help you do something you may not be able to accomplish yourself. If you have a collection account that’s been sold to a few different debt collectors, it can appear on your credit report multiple times. That information is accurate but having that one debt dinging your credit score multiple times doesn't meet the “fair” standard that Padawer mentioned.
Reducing your balances on credit cards and other revolving credit accounts is likely the better option to improve your credit utilization rate, and, subsequently, your credit scores. Consistently making on-time payments against your debt will also help you build a positive credit history, which can have additional benefits for your credit history and, by extension, your credit scores, too.
