luno support non existant

For the last 4 weeks I have trying to verify my bank account to be able to withdraw money I sent to my luno account. Their support is pathetic to say the least. They send only standard replies promising to get back wiht 2 working day, but that does not happen. If they reply it is not resolving the issue but asking for the same documents from the bank I sent already 4 times. Or they ask the obviously impossible, like a passport copy of 18 years ago. Their messaging system in the account is only showing 3 lines but not the rest on the message and their is no reply button. They only provide you with the support email and no escalation. It is really shockingly bad service.
