STRUGGLING TO GET MY MONEY BACK

On 31 August 2015 my wife tried to withdraw money from a Standard Bank ATM in Kempton Park. After completing all actions and whilst waiting for the machine to provide the money, a message was displayed on the screen stating that the request can not be completed and that the account will be updated. That evening I notice that the money was taken out of the account but never wrote back I attempted to contact Standard Bank who informed me that their system was off line. Two days later I was able to get hold of a very helpful lady who informed me that the system was still not 100% working but that she will log a query. She requested me to phone back later that same day which i did - twice. On the last occasion I was informed that the money will be back in my account by the latest the 12th of August. Needless to say I am still waiting. After phoning Standard Bank again on the 12th I was informed that they are still busy. This money is part of my rent which was due on the 1st already. How long does Standard Bank wants me to wait before they credit my account with MY money? Or am I not big enough and my salary not big enough for them to finalise this matter??
