Last year I got Optus ADSL2+ as my internet provider, paid the initial setup fee bla bla and they sent me an NBN-ready ADSL2 Wifi Modem.
Anyway long story short, I had internet drop outs and they couldn't fix it so I cancelled within the cooling-off.
I still have this modem brand new and sealed, I've emailed them twice and got no response.
What can I do with it? I cant just bin it - can it be sold?
