Ah, auto-renewals! When signing up for a service that bills you monthly, quarterly or annually, a forthright retailer will let you know when your renewal date is coming and will inform you of upcoming charges. But shady companies don’t say a word and charge you again you without notification, sticking you with the bill even after you complain—all because you were “too late.”
