I was able to opt out of the phone calls by dialing the phone number.
I had to weed through their privacy policy which is here

To unsubscribe: You may cancel your SOS subscription and revoke your consent to receive calls at any time by either (a) utilizing the opt-out procedure included in any message you receive; (b) by sending an e-mail that includes your telephone number to
[email protected]; (c) by calling 800-269-0281; or (d) by sending a written request to Worldwide Commerce Associates, 3651 Lindell Road, Suite D, Las Vegas Nevada 89103.
I called the 800# above which is a recording, entered my phone number that I had subscribed with.
The best one is I opted out of the phone calls when I signed up for the emails.
