$1 · Yellow Pages Problems - Refusing to cancel advertising

Have you had this problem? Can't stop YP from billing you for advertising despite your registered letter(s) sent requesting they stop? We have a small business on the island and we are fed up. We can't find a current class action in Canada outside of Quebec, but maybe it's time to start one for the rest of Canada. Lets know about, 1. When your issues started 2. How many registered letters have you sent 3. Are you interested in staring a class-action? Thanks much.
