No reason or correspondence as to why a claim is rejected

I submitted a claim in February as I was retrenched in December, UIF doesnt send one a letter with a bird, or an sms or an email nothing to say that the claim was rejected and to add insult to injury there is knowwhere online that tells you why and what they need to fix the rejection, I submitted all the documentation that my employer provided to submit a uif claim and the claim was rejected and no correspondence to let one know why, when i logged onto the system i seen rejected, that is all there is how do you operate like this
