Hello is standard bank trust still open

We have my father's late estate at Standard bank. We are not happy with their service. Last few months we have been given the run around by them . DIPOUH who is handling it has messed up the distribution of it. Ever since then she has gone silent . So I called front desk to ask her to call me back . She eventually mailed me starting the email ...o I see you have lodge a complaint against me ...I will come back to you ... 4 weeks later again she is missing in action .. So I lodge a formal complaint with Danie that she is not getting back to us . A week later she emails me o I see you lodge another complaint against me . DIPOUH SAID SHE SENT THE PAPER WORK TO MASTER OF COURT AGAIN IN SEPTEMBER.... 3 WEEK AGAIN NO FEED BACK .. PHONED DANIE LAST WEEK MONDAY ...HE SAID GIVE HIM A DAY OR 2 HE WILL HAVE IT SORTED... PHONED HIM AGAIN ON THURSDAY....HE SAYS HE IS WORKING ON IT.....A WEEK LATER ...SINCE MONDAY STANDARD BANK TRUST HAS GONE SILENT...
