On July 1, you relocated your business from one Detroit suburb to another. A month prior to your move, you phoned your security system provider and notified its representative to cancel your service effective June 30, the end of a three-month pre-paid electronic billing. When you received your credit card statement on July 17, you saw that the security company had billed you for another three months’ service. You phoned again that day and were told by Al Sapperstein, the manager at SEC-ure, Inc., that he would take care of the matter and reverse the credit card charge.

You weren’t concerned when your August credit card bill didn’t show an adjustment, but now that it doesn’t appear on your September statement, you’re convinced it’s time to create a written record of your requests.Write Mr. Sapperstein.
