Three months ago, we cancelled our subscription to Economic Times Magazine. Despite our cancellation, we have received a magazine every week for the past three months. However, we have refused delivery of the magazines and had each of them returned to you. Today we received a bill for 1,200 baht covering the last three months. The bill was also stamped "Past due Since we have not ordered nor have we accepted delivery of your magazine, this bill is obviously incorrect. Would you please stop sending us copies of your magazine and also cancel the bill you sent us?
