Standard Bank - Disgraceful service

I deal with Standard Bank Deceased Estates Division on a regular basis. I always contact them to obtain Certificates of Balance. to close an account etc. Last Week, 23 October 2020, we sent an email to Standard Bank Deceased Estates Division, we got an automated reply back to state that they no longer accept emails but we need to upload documents on their web portal. I registered and lo and behold I have had no email from them stating that the registration has been successful. I have tried to get hold of the Estates Division to no avail. I have even tried to get hold of the Complaints Division of Standard Bank also to no avail. Yes, I understand that people are working from home but how is a person supposed to work if they do not get the service they deserve.
