You can sue the seller for breach of the contract. The seller is accusing of misrepresentation of the contract. This clause refers to the case whenever a part of the contact cannot perform as per the details stated in the contract. His act is then contravened to the contract.
Also, there are 7 legal elements in contract: Offer + Acceptance + Consideration + Intention + Capacity + Formality + Legality.
Where Formality stated that verbal contract is a valid contract.
For your reference,
Civil Law - Law of Contract (合約法)
Contract law deals with promises/agreements. (要有承諾/協議)
Once the existence of a valid contract has been established, an inexcusable failure to perform the contractual obligations,
or defective performance (履行)of those obligations, constitutes a breach of contract. (悔約) The remedy for breach of contract is an action for damages, rescission (取消合約), injunction (禁制令)or specific performance (強制性令).
