How does SANRAL get my details?

[Berg Man]

So I sold a bike and have now been getting e-toll invoices, which I have tossed away. My question is, how did SANRAL get my details? I have never registered on any PayFine or the like.

I have also just received an sms to register within 15 days to qualify for the discount. Where did they get my cell number?
