In spite of our statements and letters sent to you on october 31, November 30 and December 31, 20,
we have received neither payment in settlement of the overdue account nor any communication from you to explain why you have made no payment. We are indeed very sorry that we must take more forceful action to collect the balance of your account 14,300 baht due since August 20, 20...
Please note that we will have to hand this matter to our solicitors if your check is not received by February 28, 20--.
We sincerely hope you will avoid this injury to your credit standing as well as the extra cost involved if legal proceedings are necessary.
