Payment claim

I had did my application in Aug 2022, and till date I have no feedback, every time I call the call center to find out my application status, they tell me that they must update my documents and the assessor has to still assess my application, it has been 5 months and still no feedback. Mapule Majafa as a team leader at the uif call center, gave me details to follow up and till date she hasn't responded. This has been the worst experience I have ever encountered. What must be done for the uif department to take my application serious.
