I received a letter from the Internet Order LLC requesting for a payment. I called customer service to cancel these CDs in 2012 and I returned the CDs back them as per instructions. I thought it was settled. I received this letter dated April 1, 2013 requesting for a payment for x amount of money. No way Im sending that kind of money. I was instructed to return the CDs to them and I did. Why am I getting a bill from them. Lack of communication from customer service. The company was www.pimsleurapproach.com/coursebooklets.
