Old mutual company is full of ******!!

Can someone tell me why do I have a policy with old mutual,a life cover I know nothing of?I have never signed for a life cover in this company but an old mutual representative keeps signing different policies on my behalf and all of these deducts on my pay slip.This is now the third time that I have been their victim since last year(2023).The other 2 times I went to their offices to enquire about this ***** and I got no explanation,I was just refunded and they promised to investigate who is the person responsible for this *****.This is completely unacceptable and it's draining.I am thinking of just cancelling the one policy I have with them since they do as they please with my hard earned money. STOP *****ING MY MONEY!!!
