Unable to cancel auto-renewal

I am trying to cancel auto-renewal for a Armor subscription, and reclaim the money taken by Netgear without my permission.

- I can't find any record of signing up for an auto-renewing subscription.

- I was informed this would be taken just a day before it was, I was on holiday and didn't see the email

- There is no option to cancel this renewal on the web portal

- the 'manage' link next to the subscription on the web portal just takes me to a FAQ page

- Trying to cancel on the Orbi app just throws an 'unexpected error - please try again'

- I raised a case with Netgear via the app, but they just sent me a phone number that I had to phone to progress the case. I phoned this, was placed on hold for 10 minutes, someone answered, the phone cut out and then they cut me off. I have limited appetite to repeatedly try this

- I have emailed servicessupport@netgear.com but have not received any sort of response (even an  automatic acknowledgement)

I am very unhappy about this to put it mildly, it seems that Netgear is using a whole host of 'dark patterns' to take these monies without the consent of customers, and prevent them from easily contacting them to resolve disputes.
