No response if I do its from pillar to post

My late husband did a will in Standard bank. He asked the bank to open a trust should he pass away. I regret the day he made that decision because of treatment Im getting from the late estate trust department. Thise people are not interested to surving family members. I was lucky that initially I was served by Kriska, unfortunately she resigned and she forwarded me David, David didn't even notified me about his resignation only find out from automated messages that now I belong to Haveshini who doesn't even reply to her emails. When you call no ones answers it takes more than a hour ringing with no response. If Im answered lucky Im sent from pillar to post.
