Pension fund

I wrote a,review on the 30th and the response was that my matter has been escalated to the relevant department, but I haven't received even a call from sanlam. I have spent more than R300 in airtime since July trying to get clarity on my claim...I always spoke with different people who told me different stories even head of department by the name of Kim I sent him an email but never responded. My HR department is no longer taking my calls even to respond to my texts.
