You can object to your invoice in person at one of our offices, by phone at 1-844-888-5862 (LUMA), or through Mi LUMA web or app. Objecting an invoice, however, does not release you from liability for payment. You must pay the amount corresponding to the average of the invoices not objected during the months prior to the objected invoice up to 6 months. In those cases where the objected invoice is the first invoice, you will have to pay a sum equal to the deposit. In the event that the average of the non-objected invoices is greater than the objected invoice, you must pay the objected amount.
