Discovery bank has no email address to send fica documents to and they froze my account

My account is frozen because I have to verify my address. I tried to use the live location thing, and it failed. I tried to upload documents via discovery bank app and it failed. I tried scanning the document via discovery bank app and it also failed. I tried all these with the banker from discovery bank and it failed. I requested an email address to which I can send the documents, and they say there is no email address to send documents to, so I am stuck. Using a bank that only rely on cellphone app is a huge disadvantage.
