Automatic renewal and number of devices

I only have one device and you now want to charge for ten. Want to cancel my subscription with immediate effect but your link doesn't allow cancellation until 2022. Why?

Hi Geroge, 

We will clarify this for you.
The GBP 99.99 for which you were charged for the AVG Ultimate (Multi Device) has been cancelled and refund has been initiated aleady on 18th.
That is why you are not able to unsubscribe.
The refund will be returned to the payment method used to make your purchase within 5 business days.

I request you click on the link below to reach our AVG billing team via live chat or call support to help you with a subscription for 1 device.
