Yellow Pages charged us for over 6 years of an ad on their site with a wrong business name - so we didn't even showing up on search. We didn't know until I searched on yp.ca and don't find our ad. When I confront to them, the answer was they not responsible for their mistake (they set up the ad). So when I wanted to cancel the service, they said there is a contract for auto renew (which I don't aware of) so they will charge for another 3 months.
ya.ca has terrible service, very unreliable, don't get any result. We won't recommend for any one.
