Repair was done
If we collected $145 / $130 and we did do a repair, the diag fee is good for 90 days for the same appliance, even if a different issue has occurred.
If a COD customer calls back within 90 days of the last repair and they paid the diag fee, we do not quote another trip fee. However, we must explain that the customer may be responsible for any additional parts and labor, if needed.
