Mee wrote to Zul offering to sell his computer for RM2,000. Zul accepted the offer through a letter posted on 5 December 2014. Zul, however changed his mind and wishes to revoke the acceptance that he had made. Zul is worried that he will not be able to revoke the acceptance by posting it. Zul therefore telephoned Mee on 15 December 2014 at 10am to revoke his acceptance. On 15 December at 11am, Mee received the revocation letter which Zul posted. Mee is unhappy and wishes to sue Zul for breach of contract. Advise both parties
