No communication or feedback

I submitted an additional investment application, using the generated form from the website using the tool provided, last week Friday at 10h46. All the documents needed attached. Got an automated response to the mail.<br> <br> It's now two working days later. No response. Nothing.<br> <br> I tried to phone their call centre, and a tinned voice informed me it was too busy. And then dropped the call.<br> <br> Terribly unprofessional, and frankly unnerving for a financial institution.
