Deceased Estate

My husband passed on in January, I had informed Wesbank about his passing, they sent me an email with all the required documents. I emailed the requested documents.

Called after a week but none of my calls were answered. Sent follow up emails to the bank but no one is responding to my emails.

Last week tried to call again and i was told that they didn’t receive my emails and again the same email 3 times. I tried to call again numerous times this week and no one is answering my calls.
