Ithuba Lottery delays approval of bank account

I access the Ithuba website to play Lotto and have found the website to be very user-friendly and notification of winnings a good feature. I have recently won a small amount that I want to transfer to my current account. I uploaded my banking details and ID successfully, however when I try and transfer I get a message that my account is not approved. I called the Lotto helpline on 18th August and the agent told me she would notify Lotto finance but was unable to advise as to what the normal time delay would be for my bank a/c details to be "approved". We are now into the third day and I am still unable to transfer my winnings! This is unacceptable from a high profile National Lottery as once my a/c is approved I will still have to wait for up to 72 hours before my winnings will reach my bank a/c! And all the time National Lottery earns interest on my money, small amount as it is, but multiply by the thousands of internet players in a similar situation, this becomes huge! Shameful!
