Ang Tiong offered to sell his pharmacy to Zol for RM1 million via letter. Zol in reply gave a new figure which is less than RM50,000. Ang Tiong was silent as to the offer. A couple of days later Zol changed his mind and agreed to the original amount. Ang Tiong refused to sell and Zol claimed a contract has come into existence.

Advise Zol.
