I resigned and served notice till the 7th February 2025. My Pension Fund Claim was processed on the 14th March 1 month after I left the company after I made then aware. I have not been paid for my outstanding annual leave days I has 19 days. Momentum tell me that they still waiting for FNB to respond to their emails for payment to be processed but they are not responding. 3 months have passed and I have not received any single cent.
