I'm in New Zealand, and Yelp shows my business some 3 miles (5 Km) away from it's real location.
OK, I tried to start a business account on Yelp so I could correct the address etc., but no, there is no Yelp NZ, and in Yelp from any other country it doesn't recognise my business or address.
So I tried to send Yelp.com a message, but cannot do that as it tells me it can't find my business. What the hell???? So I sent a message as a normal "user", and it said it can take up to a week to respond.
I am mega pi55ed off with a lot of the IOS 6 update, and this really has hit the nails in hard.
