DEBITING MY ACCOUNT INCORRECTLY

On the 1st of December 2014 and the 2nd January 2015 I received a notify me sms stating that Sanlam had debited my account with R2 500.00 for each month, totaling to R5 000.00. This was strange as I have never had any affiliation with Sanlam ever. I then called my bank who informed me that I had to call Sanlam directly with the information my bank had given me as only they can sort the problem out. I then called Sanlam who asked me for my information and the details appearing on the notify me sms 3 times, finally coming to the conclusion that I dont appear on their system, however the reference number that appears on the said sms seems to be a policy I asked them what I would have to do to prevent this from happening going forward. They didn't have and answer for me and still dont after weeks and after I had sent them my account number, file number, reference number, serial number, etc given to me by the bank. This is regarded as ***** and to be perfectly honest Sanlam is not bothered at all.
