Unfair practices and questionable advice

I app**** 29 days ago. Last week, I was told they couldn't find my application, that they would cancel that applicatio (how, if they couldn't find it) and reapply. I did this only to be told that I have an existing application on the system. I was also told that if you earn too little or too much, you're declined. Yet, the minimim income is R1850. Why are SASSA pensioners being declined for earning too little? They either decline you or 'lose' your application
