Otter AI starts recording my calls: I have never authorised it & my Account settings say disabled

[Sally_]

I'm a coach and have always refused to accept Otter AI for confidentiality and trust reasons. It is a business risk. 

Today Otter AI has started recording all my calls automatically. I've never authorised it. I logged on to my Account settings and double-checked - it is all disabled. 

Why is this happening and how can I change the default to get rid of Otter AI? 

It might be useful to have it for non-coaching calls but I want to be able to OPT IN.

I do not want to have to spend hours trying to work out how to OPT OUT!
