Emerald Life *****ulant company

Emerald value has been deducting a premium of R353 a month since June 2020. I only now noticed this deduction since payslips were only given to employees in December 2020 due to the lockdown and I only received my payslips 2 days ago since I transfered elsewhere. There are no Emerald offices in my town and getting their contact details is a nightmare. Please if anyone can assist or advice how I can get my money back from these **********.
