Worst service ever!!!!

These people are useless. Getting through to them is next to impossible. You stay on the line for 30 minutes before your call gets answered, then it's a struggle to hear them properly as the line is so bad and low volume. I have been waiting for my Provident fund for nearly 4 months now and today I got a new excuse whereby the resent my banking confirmation request and it then still has to go to SARS. This has been told to me in the beginning of December already yet now the process is still in its infancy. Can someone please advise me as to who I can communicate with regarding this issue with Sanlam as I have given up calling them because after all this is money I am owed not the other way around. I have already logged a complaint on their website in last year and have yet to hear back from them.
