*****ulent activities on my pay by Sanlam members

I have a policy with Sanlam, been with them for over a decade, I received my payslip today only to find there are recently added policies there each for over R300 and I never authorized those, I am very aggrieved and honestly don't know how to trust them moving forward knowing they can let such *****ulence take place when I have trusted them with my money all these years.
