ACT Fibernet — False promises and rubbish customer service

I'm a Act BB Customer with ID 10777653 for close to 5yrs. I usually pay my monthly bills and never trust the offers act bb offers whilst I pay the bills.
For a change, I got the pop up asking me to pay 6 months up front and get a free WiFi router and I wanted it too so I decided to pay the upfront.
To my surprise none of them came back to me after so many days. Today the 16th Jan I called up and the advisor over the phone carelessly says I'm sorry the app is newly developed and we are not giving any routers for old customers and it's only for new customers. His communication manners beyond average.
I NEED MY ROUTER FREE OF COST. I also have screen shots of the app saying free router.
