NMX Health Radar and NMX Dividend Machine review: Newsletter subscription I did not renew

I don't even know how this company found me. I received one newsletter in the mail. Then I received an e-mail saying please stay with us and renew your subscription which I did not reply to. I did not subscribe and I can't afford it on a fixed SS income. The charges on the newsletter say $42.95 per year and I was charged on my card $39.95 and another charge for the dividend machine of $109.00. I can't afford these. I'm on a fixed income. The phone number is always busy and you can't get through. When you send an e-mail to the address they suggest on website to help unsubscribe, you get another e-mail to confirm your e-mail subscription which I don't dare reply to. This is a scam and I am having my bank put it on dispute.
