Double Deduction i'm very frustrated

Please somebody investigate my payments I have received an email to say I have missed the payment after I have just added my child on my greenlight policy and I called the Old Mutual Financial Adviser to assist as my policy was no longer activate after adding my second child. I told him but the was a deduction of R567 on my pay slip for August, September and November after adding the child the deduction was supposed to be R649.now the Financial Adviser told me Old Mutual they can't trace where is my payments.

I then change the method of payment, so they can deduct from my bank account as from 15th of November to my surprised my account was deducted yesterday the 1st of November (R564) and from my pay slip the was a deduction of R567 on the 15th.

I have also asked the financial Adviser in writing to remove the two policies as soon as possible 69253P ********** 28 69253P ********** 32 Please assist with the matter as I can't afford the double payments and it as seems Old Mutual doesn't know where my payments are, but the employer confirmed the payments. I’m disappointed how Old Mutual operate now my budget is mess up.
