Sanlam fails to pay wealth bonus

My reviews dated from 19th May refers.

Yes your call centre has contacted me, paid me R500 as an apology for the delay in the payment of my wealth bonus and the promise that it would be paid by the end of this week. Friday has come and gone and still NO PAYMENT!!!!!!!!!!!! There was a long story of how they are updating their system hence the delay. And due to this they are now unsure of what to pay me. Did you let your clients know that you would be scheduling maintenance on your system and that it may mean a delay?? Is it my fault you failed to pay at the correct time and now my bonus has increased causing you to be unsure of the correct amount due at time of payment date????
