Attempted car *****ing

On the 9th of April(16:30-17:00) i parked my car right in front of the shop, went in to order and sat down and ate, when i finished my food i got out and realized someone tried to break into my car, a full restaurant of people did not see anything, and the only response from managers on duty was that they do not know how to use the camera system, i have contacted the store numerous times but every time they just said the will call me back with info, but i have not received any correspondence. All i want is to see how it happened so that they can prevent this from happening to other customers, there were no security guards around which i find strange.<br> <br> Please sort this out for me!!<br> <br> Regards<br> <br> Jurie
