How about this then? Many restaurant owners, including the ones I mentioned, are unaware of the existence of these unofficial ordering channels (websites, phone numbers). They claim that they did not sign up for any of this. My wife recently was tricked into calling one of these fake numbers on a fake, but official-looking restaurant website. The person on the other end pretended to be the restaurant that we wanted to order from. But my wife grew suspicious when the person knew nothing about the menu. You keep talking about contracts. But simply saying that 'you signed a contract' does not make it true.
