Good Day

I'm owed April and May salary from my employers.
Because of the Corona Virus I took it slow and told them I would fill in the papers to submit
and receive my UIF Payment.

They then told me UIF payments is outstanding. So UIF won't pay anything to me.
My payments to UIF has been subtracted from my salary for the last 5 years.

What route can I take to address the issue.

Thanks in Advance
Jaco
