Love to pay but UIF don't want my money

I have been trying to pay UIF for over 2 years for one of my employees. Every time I call they are not equipped to handle the query but they will not connect me with their IT department. I get a ref no and they follow up saying it is closed or asking for feedback. I remind them that the issue is not resolved and they send me the standard instructions, which do not work. I call them every single month and I never even get the consultant to go into the system to understand the error I am getting.
