I received no notification of the additional charges being billed to me until I received a collection letter on behalf of this company. No where during the offer nor the paperwork or emailed recent that I was sent was information about potential Guthrie charges. When attempting to contact the company, after receiving the notification from the collections agency I was unable even after scouring the Internet to find a valid phone number for them. To receive zero communication from the company but to be turned over to a collections agency regarding this "unpaid" balance is ludicrous.
