ear Mr. Simpson :
Yesterday I received from Mr. John Hays full information about your outstanding account with his company, together with a letter authorizing me to collect the amount (8,000 baht) which you have not settled.
You have not given Mr. Hays any explanation of your failure to meet your obligation. Therefore, I hereby notify you that, unless I hear from you within seven days, I will institute legal proceedings for the collection of the sum herein mentioned.
