My husband and I got this coffee pot as a wedding present. We have been using it since June and have beenough absolutely thrilled with the quality of the cofree it produces as well as how long it retains heat! About a month ago, we starated having issues with the lid, however. It would periodically get stuck open or closed and the thumb lever becomes unresponsive. The problem has grown gradually worse and more consistent. Not sure what to do about it or how to order a replacement. Customer service help please...?
