The problem with the credit repair service (mycreditlocker) that was mentioned in the previous post is that it can end up doing people more harm than good.
First, when you dispute online (part of the package they promote, on the website), you effectively give up one of your most valuable rights under the Fair Credit Reporting Act, because you can't use certified mail/return receipt to prove the delivery date of disputes. This is critical, with regard to the 30 days that the bureaus are allowed to investigate the dispute.
Second, by using template letters, you vastly enhance the likelihood of triggering a "frivolous or irrelevant" response from the credit bureaus. You effectively have only one chance at disputing a particular item, because the dispute will be recorded by the bureau, which will not be willing to entertain another dispute. So this can be a terrible waste of a valuable option.
Third, the "tri-merge" report is a bad idea, because you want to see your separate reports from the individual bureaus, to leverage any differences to your advantage. For example, to simplify for purposes of illustration, if your credit profile is strongest at Bureau A, then you should apply for credit with creditors that access credit info at Bureau A.
In sum, you can get better results for yourself while at the same time saving money, by avoiding these kinds of offers.
