I received a collection notification with an almost 100 percent interest charge on an unknown and non-notified balance. I used Monet Dental two years ago and always signed and paid cash or credit up front for any balance owed as required by them. I have not received a phone call or an invoice since. Fast forward two years later and I get a collection notice with extreme interest added. In an effort to resolve the issue I left multiple messages with both the collection agency and Monet Dental via phone and email. I had two sources of an insurance, which sometimes causes confusion when seeking payment. But Monet never attempted to get any unclaimed balance resolved, just sold me to an agency. In my message I asked for a phone call by Monday, November 22. I still have received no response. I have no idea what the charge is for, have never been notified of such charge via phone or email, never been given the opportunity to address it, and when inquiring with both the organization and collection agency I received no response.
