Sasol rewards - Absolutely useless as it does not work

Sasol reward is useless. You registers, then says not valid email or email already exists. Then id is not valid or does not exist. Then your phone number comes up as suspicious and they won't let you register or login. Then THEIR OWN CARD NUMBER IS NOT VALID OR DOES NOT EXIST. Why bother having a rewards card if people cannot use it. There is no support to register this card or reset, trust me I have tried, just get given another email and no response.
