Sanlam service really bad!

My policy has reached it’s maturity and I requested a 1/3 lumpsum payout! All the documentation has been sent and received by Sanlam. I have now been waiting for 3 weeks and see the estimated date for completion is only 18 June???? Why will it take so long - for 40 years my monthly payments were made but when it comes to paying out 6 weeks!! This is unacceptable - we need to live daily survive with no jobs and now Sanlam takes 6 weeks to make a payment (which out of past experience will not happen anyway). I must mention that if I had a choice I will never deal with them again - e-mails to them gets a standard reply sent back and phoning the offices is endless holding on with no results! I need the payout urgent!!
