Dwolla Careful of $3 monthly fee- "instant" service deceptively activated, no verification, cant cancel. Internet

Dwolla was very responsive with their customer service, and they credited me $3 to pay the month's fee for the service I did not know I was signing up for.  They did not tell me however how to cancel that service, nor was that easy to find.  I did find it finally, and they did reply again telling me - you go into "funding sources" and deactivate the instant service.

I have a real problem with recurring services that sting you like this - they make it seem like it's part of another thing you're trying to do, no secondary validation (which really needs to be there to constitute a legal e-signature), and next to impossible to cancel without paying a fee. My frustration with that was mitigated by their responsive and helpful customer service.
