Sanlam Umbrella Fund complaint for poor service

I have had the worst service from Sanlam Umbrella Fund(SUF) and Sanlam DRA Funds and Schemes department. I'm a former employee of Sanlam and I resigned last year. I was told my claim(of withdrawing from SUF) will take 3 to 6 weeks counting from 1 December 2019. This week was the 5th week and I have been struggling to get any feedback as to how my case is going. I don't know what is happening, who's handling it, what's outstanding etc and when I will get my money. Every time I ask for feedback on my case I just get a generic reply which doesn't really help at all.
