GSRA Automatic Renewal??

I've had GSRA for a few years now - I think since 2015. My present coverage is good until late June this year. I've kept it up because we've been taking long trips each year. But we're not sure if we will be travelling more than a few hundred km from home this year so we've been pondering whether to renew RA or not (new truck and trailer in 2016).

Yesterday I received an email from GSRA with the subject: Please update your account information

The email then states:
"For your convenience, you have elected to be enrolled in Automatic Renewal...

Per your request, we will charge your credit card on file for annual dues prior to your membership expiry date..."

Then says to call a number to update CC information.

I don't recall ever having agreed to "Automatic Renewal" and haven't given any permission to charge my CC. I certainly didn't do it knowlingly. The email doesn't even tell me when or how much will be charged.

I'm concerned about this seemingly blanket carte blanche GSRA feels they have to charge me whether I want to renew or not (I haven't decided yet but this is making me want to cancel for sure).

I assume others have received the same cookie-cutter email. What have you done about it? How do you feel about it?
