Before you do business with a Cingular reverse search directory you will want to make sure that they are reputable
. There is a really easy way to do this. First of all, all of the reputable directories charge a fee. Cingular charges the reverse directory for access to their databases, so you cannot expect to search it for free. Secondly, the reputable directories offer a 60 no-hassle, no-questions-asked satisfaction guarantee. If the number you are searching for is not contained in the database you will get your money back.
