Magazine Renewal

The real problem comes when you have multiple "free" (low-cost) subscriptions that came from filling out surveys like I did on Biz-rate. I received 9 months or so of two mags, then got new free subscriptions for the same two mags "that would take 6 to 8 weeks to process". A notation with the 2nd deal said to cancel auto-renewals by some upcoming date, but then I received cards in the mail regarding cancellation of my automatic renewal [which I believe is for the original deal---that I had originally cancelled any auto-renewal---so i shouldn't be receiving cancel cards for that deal].
I have no doubt I will be receiving overlapping subscriptions of the same magazine [something like this happened 8 years ago], but what I really don't want is to receive THREE of each, while being charged full-price for one of them, and trying to get my $ back.
I found at least 9 phone #s for this place, and they all give the same woman robot (Is that you "Rachel--from cardholder services" ?) Some things you need to be able to TALK to a human about.
P.S. while I was typing this, on hold with 800-601-1958, I actually got thru after pressing a few zeros and a long wait !!
