Salt provident fund service is horrible

I have app**** for my 2 pot system on the 25th of May and was told that I would receive the payment in 4 weeks. I have now called them for the past 2 and a half weeks and I keep getting told that payment should be done in 4 working days. I spend hours on the phone with no joy and it's becoming frustrating as I get promised to be called back and receive payment as still nothing
