Unfairness from sassa

I app**** for a social relief grant from sassa.. My application was declined.. It is claimed that I am receiving an income from other sources which I have no knowledge of. I have been unemployed since April 2019, and have not worked since then.. I am not even receiving anything from the government.. I would really like social development to tell me which monies am I getting and from where.. As a South African citizen I feel I also deserve fair treatment like other citizens.
