Who can I contact regarding disputed late fees? We have submitted a written complaint & have put in a calls, but have gotten no response. These late fees date back to Jan of this year & have continued until present. The invoices never stated there was a past due balance, so late fees every month didn't make sense & just kept being added & paid each month by us. We are obviously disputing these and would like to be refunded the monthly fees as the past due balance would have been paid immediately if invoice would have stated there was a past due balance. We would really love to clear this up, but continue to get no response.
