Babu lives in a rented residence in Kuala Lumpur. His late father had left him a house in Penang. Babu has decided to sell the house and utilize the proceeds from the sale to purchase a house in Kuala Lumpur.

Babus good friend Joe, who lives in Penang, had sometime in the past expressed his desire to purchase the house. On 19/11/2020, Babu wrote to Joe offering to sell his house for RM 350,000. Joe received this letter by post on 21/11/ 2020. On 26/11/2020, Joe posted his reply accepting Babus offer.

In the meantime, Babus neighbour, Beng who was aware of Babus intention to sell his house, offered to buy the house for RM400,000. Babu decided not to accept Bengs offer for the time being since he wanted to first revoke the offer he had made to Joe. Babu then wrote and posted a letter to Joe on 25/11/2020, revoking his offer.

On 27/11/2020, Joes wife, Sandra, noticed a beautiful house next to Babus house which was being offered for sale at only RM300,000. Sandra asked Joe to revoke his acceptance of Babus offer. Joe tried telephoning Babu on 27/11/2020 but he was unable to contact Babu. Later, on the same day, Joe wrote and posted a letter to Babu revoking his acceptance.

Beng revoked his offer made to Babu on 27/11/2020 and instead bought the house situated next to Babus house for RM300,000. Babu now wants Joe to buy his house. Babu received Joes letter of acceptance on 27/11/2020. Joe received Babus letter revoking his offer on 27/11/2020. Babu received Joes letter revoking his acceptance on 29/11/2020.

Advise Babu whether there exists a valid contract between him and Joe or Beng for the sale and purchase of his house.
