Canara Bank ATM — Non delivery of cash

On last Sunday, 20.09.2009, at 12 o clock in the noon, I went to Canara bank ATM at Tri nagar branch.
After entering the required info. I requested to withdraw Rs. 10,000. Accordingly the Cash was came out and within a couple of seconds it went back into the machine.
Consequently my saving a/c got debited with Rs, 10,000/-
I was asked to wait for 15 days.
Please suggest me the suitable course of action.
