POOR SERVICE FROM STD BANK'S FOREX FUNCTION

I submitted an application to draw down some rands from my Standard Bank CFC dollar account. I mistakenly dropped a digit on my account number on the application. Is it unreasonable to expect that whoever processed the application would send me a message explaining that to be the problem? No!! Nothing happens!! It is up to me then to try and track down why the money has not been paid until after a full week of fruitless endeavour I am finally told that the transaction could not be processed because the account was not recognised. It is also not the first time that this has happened.
