Sanlam deducts money - I AM NOT A CLIENT OF SANLAM

During last year I noticed that Sanlam was deducting money for THREE policies which I did not even get, and this from an account that I never use or give out the number to anyone - upon contacting them they apologized and cancelled the policy - and refunded my money.... Guess what - the same policies was deducted again in February!!! I sent through a complaint with the previous emails the sent to apologize, but hey, guess what they once again deducted money for March!!! No I want to know how do Sanlam get authorization to deduct money for a policy I didn't sign up for? And after correcting this they go and do it again??? Isn't this *****????
