ATM Dissappointment

I went to the ATM to draw cash and immediately after that I got an sms to indicate to me that my money has left the account and to my surprise the ATM machine was still not dispensing my money. Waited for enough minutes until a slip that shows that the Dispensed amount is Zero and then I decided to leave the ATM without my cash. Called their call centre and i was told that it might take 24 hours to 14 days for the investigation to complete and until then I must just be patient. How am i expected to be patient when the reason I went to the ATM in the first place was that I needed my money and now I have to wait for days before my money could be returned which is also not a guarantee. I decided to go inside the bank because I thought something will be done and I will get my money on the spot and to my shock, same story, now I am told it will take up to 7 days for the bank to determine what exactly went wrong and I must be patient. The sad part of it all is the fact that It was my last money for the month and now i am very inconvenienced and have lost interest with the bank itself because how and who is going to lend me money whilst they are still busy with investigations.
