For the better part of the past year, we have been working with XXXX to resolve an issue related to an early termination fee and failure to return equipment due to a temporary move to California for work. We were advised by a XXXX customer representative in writing that this error should not have occurred, yet to date it continues to persist and we have received several phone calls and written notices attempting to collect on an unpaid amount totaling {$1000.00}. This amount was acknowledged in an email by a XXXX XXXX XXXX with XXXX as an error on their part and that we did not owe this amount to their company. They have sent this amount to collections ( via Convergent Outsourcing, Inc. Acct No. XXXX ) XXXX now and have failed to act on the agreement they have provided in writing to us. That agreement stated that they actually owed us {$140.00}, yet this has not been refunded accordingly. The XXXX case number referenced in this case is XXXX and through their debt collector as case number XXXX. We have records of over a year 's worth of telephone and email transactions stating that the XXXX 's did not owe the amount requested, yet as of XXXX XXXX, 2015 it still remains unresolved.
