Good Morning All,
I have received an em ail advising that my premium subscription is due for renewal next month, at the cost of AUD $109.99 for up to 10 devices.
I don’t need anti virus for this many devices, just for 1 device, how do i change my subscription to reflect my needs?
Thanks and have a great day. 
See if this helps you:

I personally would also get away from auto-renewal since that’s probably not your best price.
You can cancel it here,

If you don’t have an order # use 00000000 then explain your problem.
Thanks so much mate, I have sent them a request to cancel my auto renewal, and told them the type of AV I want.
Have a great day, and stay safe.
Bill.
You’re welcome. Enjoy your day as well.
