The Business Provisioning team have dedicated resource for handling escalations raised against Business classification orders.
For any scenario where an installation has been signed off in error (i.e. the order has gone Service Given or beyond without the ONT having been installed), there is agreement between the Business Provisioning teams and Service Delivery that these should be accepted as escalation cases under the Provisioning Error category if raised by the retail service provider. 

These will likely be received via email, as interactions and escalations cannot be opened on Portal orders in a Closed status. Where this is the case, and the escalation has been raised due to no ONT being installed, the RSP will submit an escalation case to BusinessFibre Escalations@Chorus.co.nz for the attention of the Business escalations team to be accepted and managed accordingly.
