No response on uncompleted order

On the 27th of April 2019, I app**** online for an upgrade on my existing DSL package to 10Mbps Unlimited Home. The terms of the agreement is, since I'm signing up for a 24 month period, that I will receive a free modem. They delivered, instead of a modem, a wireless repeater. I have been struggling with multiple calls to 10213 to have this sorted out. It is now 30 May and I still don't have my router. Each time the excuse is: Our systems are down, can I take your details for callback?
