Normalize checking with Department of Labour your Name and Employment Status.
Some companies you submit your CV to, registered you for UIF so that they can claim money to themselves.
Dial *134*843# And check employee registration status, they will ask for your ID, initial and surname. And then they will give you a list of companies and ask you which one you work for, if (as far as you know) you don’t work for any choose that option and then take it from there
