Old Mutual *****ulent

I am sick and tired of Old Mutual and its employees, I received an email informing me that there’s a new policy that is implemented in my persal number which I don’t even know what is it for,I never gave consent to Old Mutual to deduct R154.00 for policy ref nr: ***B0, I have no knowledge of it and it’s now the 3rd time this happening. I am thinking of taking this further and open a ***** case to whom ever is doing this. They must show me when did I sign documents consenting them to implement this policy, this company is full of ****mers and *****sters, am so annoyed.
