Unauthorised debit order, confusing phone call

I have checked my account this morning to see a R400.94 and R60 deduction.<br> <br> I received a phone call a week back and she told me something about a bonus payment from a previous policy I had with Auto and General, which is why I listened to what she had to say. However she was very unclear on the phone, I had to ask repeatedly why exactly she was phoning me.<br> <br> She confirmed all my details and at the end of the call I confirmed with her \ this is not a new policy
