[Silhouette]

Presumably this is why there is a trend in consumer rights legislation towards being explicit that anything a buyer has been told by a seller or actively told the seller before the sale is material to the contract of sale regardless of the seller's small print that says "This contract of sale we wrote by ourselves and won't negotiate with you and only this contract means anything". Then they can't promise the world to get the sale and then wash their hands of any resulting commitments two seconds after they get your money. Which seems entirely fair and reasonable to me, whether the promise came from a real person or a chatbot.
