Ahmad, a supplier of school equipment sent an email to Mohammad on 24 April 2019 requiring him to supply her a quotation of 400 units of school desks. On the same day, Mohammad sent her the requested quotation at total price of RM12 000. On 26 April 2019, Mohammad made an order of 300 units of school desk to Milli company to be delivered to AHMAD. Ahmad on the other hand had made a purchase order to PVC company on 28 April 2019 for the supply of 400 units of school desks at the price of RM10,000. It was agreed that Ahmad paid half of the price, while the remaining balance was to be made at delivery scheduled on 5 June 2019. Two days before the delivery, the factory was seriously damaged by a flash flood. Consequently, PVC company was unable to deliver the order as agreed. On the same day, Mohammad called Ahmad requesting her to specify the date of delivery of the 400 units and make the payment of the quoted price. Ahmad refused to pay as she claimed that she had never made an order from him. Mohammad threatened to sue her in the court for breach of contract. Meanwhile, on 5 June 2019, the PVC company informed Ahmad of its inability to supply the desks. Ahmad was very upset and wished to sue PVC company for breach of contract and refund.
