This same thing just happened to us and was costly on a $16k invoice (@3.5%)! I share the frustrations and deep disappointment with Intuit Management for what feels like manipulation by automating a service we never wanted to offer.  The right way would have simply been to make us aware of this feature and only allow activation when the client opts in. 

Why did they set this up?  I believe it's simply because it's quite profitable and easy to slide in without notice. Very frustrated and disappointed. I would have expected a higher level of integrity from this brand.
