Sanlam making it impossible to contact or any attempt to contact them, regarding my payout.

I have requested my Provident fund pay out to my bank account (Withdrawal) as I left the fund. Sanlam phoned me and confirmed and wanted to know what I wanted to do. I said withdrawal please. Got SMS the next day asking me to reply yes to confirm withdrawal... I have been replying yes for a week now and keep getting the same SMS everyday. I sent a mail enquiry on the email *** and week later still no reply or phone call. Phoned Sanlam support team 6 times in the last week. Every call holding for 15 to 25 minutes where I eventually have to put down the phone. No answer.. no one home? Requested as per other instructions for them to phone me back (did this 3 times).. Still no call. I want and need my money and they are not making any attempt to pay out. Actually making it impossible. I do not know what to do anymore I have tried contact them via all mediums and channels they provided me. Why?
