Aspen Dental foisted this plan on us in December 2019. Revolving plan @ $159. 00 per month, interest $69.63 per month for this promotional plan. If not paid by December 2023, higher interest would be assessed. We paid each payment in advance of the due date and the entire $5157.52 balance in full before the due date. We are being assessed about additional interest fee of $25.67. By definition, the revolving plan states that by paying the balance in full, you avoid any further interest charge. Will be discussing with BBB and attorney. Avoid this company and staff who spew a wrote answer like robots. User's recommendation: Do not use this company. No customer service, self-serving.
