IUA Not paying out

I submitted a claim for loss of income due to the COVID-19 virus and me being retrenched for 3 months, receiving minimal income. I waited for over a month only to hear that they won't be covering me because I am only temporarily retrenched, then they canceled my cover because I am unable to pay I phoned them again telling them that I haven't received an income for the month of May, they told me to resubmit my documents and they will come back to me within 7 days, I then submitted the documents a week ago and there is still no response, not even any mention on the self-service app or anything no phone call or email nothing
