I signed up for their service, but after finding that they didn't provide what I had hoped, I called to cancel my subscription. They offered half a refund, but that wasn't enough, and I demanded a full refund.
They finally did so. But within the next day or two, I started getting huge amounts of spam, which I never had before. Despite Instant Checkmate's response in 2015 to another complaint just like mine, they say you can click "unsubscribe" on each email. I tried that, and it didn't work.
My email just gets thrown around to more and more different "mailing lists" that I never wanted to be on. It's so bad, that I had to get a new email address.
Review about: Instant Checkmate Subscription.
Reason of review: SPAM.
Preferred solution: Public appology, press release stating their policy to send spam, and a change in policy to not send any promotional materials at all..
I didn't like: Company signs you up for spam.
