1Life has signed me up for a policy I'm not aware of and taking money from my Sassa every month with out my consent .I did not sign up for any policy and want a full refund as I never agreed to this.When trying to call them they drop the line or never get back to you with any actual feedback. I'm a pensioner and I want my money back immediately
