The insurance company is responsible for this charge, I was and presently am a Federal employee and medical /dental insurance is extended 31 days after separation from employment. I left my job the same month I visited this dental office, they are aware of the 31 day extension and refuse to bill the correct party for this charge, the dental insurance company. I 've regained my Federal employment status and hold the same insurance. They sent this account to collections in error. They need to bill the insurance company and remove the fraudulent charge off of all my credit reports, they have caused me a tremendous hardship.
