Money **********ly withdrawn from my account

On the 31 March 2016 at about 07:00 I went to Standard Bank at the Shell Garage Extension 5 to Draw money. I put my Card in and it requested for me to put my Pin, once i did that that screen went blank, I tried to cancel my card but nothing happened, I ran to the car to get my Cellphone and call Standard Bank to cancel my Card but I think they somehow jammed the signal because i could not get through to Standard Bank, I even called from my passengers phone. Than i saw a lady approaching the machine and went in after her but by the time i got there she was walking away from the machine, when i asked her did her money come out she said yes and i asked her did she see my card and she said no. I left Shell Garage and went to work, on my way i Received two sms's first R1000 and than R10000 was drawn out of my account. When i got to work and phoned Standard Bank they said R1000 was drawn from Engen and R10000 was swiped at Pick n Pay Lenasia. I have a case number: CAS25/4/2016. Some how i believe that this is an inside job with the Standard Bank and Shell Garage. The only way that Shell and Pick n Pay will provide footage is if the Polices or Standard Bank Approach them.
