Hi RoyinBrayPark,
Appreciate your concern surrounding your Gateway Modem and Telstra TV not being delivered at the same time. We often find out warehouse send these devices/hardware separately in occasions so my apologies for this, something we are working to chase up and rectify ongoing.
For us to chase this up, please chat securely with us at LiveChat (http://tel.st/hsc3) or by calling our teams at 13 22 00 to investigate this further
