Superfast

I have been trying since the 20th April to complete my loan application everything was approved just needed to verify my income. I have been trying to verify my income via superfast which seems to be a problem as there is a message saying that there is a problem with TruID and that i must call the support group. I called and spoke to Nathan on Tuesday 25th and explained everything to him and the more I am trying to tell him that what he is explaining to me I am not getting those options on my side and then he could not explain to me how to do this on my banking app. He promised someone would call me back in 20mins that knows how standard bank app works. I received a call 2hrs later when my phone rang once and then stopped and the next morning the same thing. I did not even get the chance to answer the call or speak to anyone. The debit check is done and my process is on 80% complete. I have sent numerous emails and never get a response. Very frustrating
