Theft from old mutual

I have an account with old mutual, which i joined 2017 if im not mistaken,,, since 2024 one of their reps is redeeming my points, countless times ive been trying to stop this with failure,, ive written statements with SAPS that too is not enough moving from pillar to post to resolve this with failure, in such a way that i had to cancel my policies, with pleasure they did that,but to resolve my issue of these points nothing has been done till this day, Their head office has failed,, what next??
