I have called the customer service numbers 1-978-299-2298 and 1-800-326-0598, and on both numbers u get the same recording. The product ID number does not exist in the places that the recording says it does. There is no product ID number on my invoice or on the newsletter. I have waited for over an hour for a customer service representative to speack to me at these numbers as the recording promises the next available representative will be on the line please wait. This is ridiculous. Why would any customer of any company, good, or service have to wait any more than a few minutes. This is terrible service. I don't understand why it would be so difficult to speak to a customer. I ordered three books from the Natural Cures commercial, and thats all I wanted. I want my subsciption cancelled NOW and I should not be charged for the longevity it takes for this company to cancel my subsciption to the Natural Cures Newsletter. I can be reached at my email.
