If its free then there's possibly an issue.
One common cause of confusion is that OPtus "charge" $6 on the bill. Lower down they credit $6 back automatically on the same bill. Check that but if you are being charged contact OPtus and they'll cedit the amount manually and hopefully fix the billing issue.
Nope, rang them and was told the charge for the channel pack was for the mini.
One channel pack free on the mighty but not on the mini which I think is BS.
Dont recall seeing anything in the fine print about that.
Needless to say the ‘not so free’ mini is back in its box and cancelled.
Are both boxes from Optus? Both are being used in the same network/home?
Basically the only benefit of leasing fetch boxes from Optus is that a pack will work for no extra cost on all devices.
I would contact support again as you do sometimes get people that have the wrong information..
The only reason I could think you might get charged is if you added a pack before removing the existing one (so briefly 2 packs were registered at the same time). You can change the pack any time as much as you like, just make sure to remove the old one first.
PS I think you have to enable multi room. Did you do that? Could you see fta recordings from the main device on both devices
