Double trouble

In the middle of last year an old mutual agent Mr S Ngcobo came to my place of employment,I took an educational plan which was R200 and later took life cover for R200 .…a few months later I asked him to increase my premium for a higher cover and he gave me a cover for R469 premium .In November another lady from old mutual Mrs R Naiker came to my place of employment and checked which cover I had taken out..she then informed me that Mr Ncgobo had made me a beneficiary of my own life cover and given me an incorrect cover ,she then offered to sort it out and offered me a better cover which pays out more for a lower premium,She said I would be paying R387 for my life cover and she will put a better educational plan which I'd pay a bit more but for a better benefit at R350 and she would cancel the other 2, she told me that since i have a stop order it will cancel after 3 months and the new cover will then deduct in February. All of that did not happen I was debited for 4 premiums in January,R469,R350,R387 and R200 which is for 2 Life covers and 2 Educational plans and once again made a beneficiary of my own life cover...I called Mrs Naiker and informed her ,she said she will sort it out and i would be refunded which still did not happen, I was once again debited for 4 premiums again in February and when I told her about it she told me that unfortunately because I have a stop order they can not reimburse me. All I want is my money back that I was over charged and the correct cover and beneficiary details, that's all. No Stories.
