Policies being deducted without my permission

I am a very unhappy single parent who is the only breadwinner at home. I have 3 funeral policy with old Mutual. After my son turned 21yrs old I was called and advised to open a comprehensive policy for him of which I can claim a cash back in 5yrs time, of which I did in April this year. But since I noticed that why is my salary not adding up than I discovered that a consultant added 3 additional policies to the existing ones that is being deducted from my payslip. It's been almost a year now. I made a complaint at my nearest branch but I am so upset with the poor customer service I received telephonically with a consultant named Natasha who was rude and sarcastic when I was enquiring. I need advice this is so wrong In so many ways.
