NO Service recieved!

I paid in December of 2019 to back pay UIF for my domestic worker, (from the time the UIF office re-opened after their bankruptcy), who we were going to have to let go. I received a case number and that is all. I have emailed numerous times and phoned as well. The answer is the same there was a problem but we are fixing it. I don't what the problem was but now, my ex-domestic worker wants to take me to the CCMA.
