Reference without pi code

I made a withdrawal of R1500 on Saturday morning around passed 12;:00 midnight. It tried to transfer to my account unfortunately the bank was offline. So I opt for cash send. I received the message from ABSA with reference number without the six digit code. I wrote to them ,no response yet. I don't understand why we keep on playing their games. There's always a problem when it comes to their withdrawal. Sick and tired of their tricks.
