Sanlam Corporate - Pension Fund Withdrawal

I have been trying to contact Sanlam "Corporate" for the past two weeks regarding withdrawal of my pension funds without any success. I have been provided with various log numbers for my emails. I have called and been placed on hold countless times with the longest call duration being over 60 minutes -this is costly and stressful! I attempted to use WhatsApp but I receive the text "... unfortunately, this service isn't operational at the moment". This is extremely frustrating! How exactly is one supposed get assistance as Sanlam is not available on telephone line, emails, WhatsApp service and Sanlam portal does not help at all. Horrible service! Sies!
