Persistent Personal Loan Spam

I keep receiving spam SMS's from Sanlam regarding personal loans, and keep opting out, but it doesn't stop.

Some years back I contacted my broker and threatened to move all my business from Sanlam if this doesn't stop, and it stopped for a bit, but now it's back

I will apply for the loan if I want it - and I think less of a business that should give me sound financial advise, guidance and products if they keep pushing irresponsible lending
