| Paul,
I would write to Sainsbury's too. As CK says, they should keep a log of all incidents that happen on the forecourt. From your description I was wondering if it might have been a small independant (Dealer) filling station (to have no cameras on the pumps), but as it is a Sainsbury's, I am pretty gobsmacked that they didn't have cameras.
As Andy says, follow it up with the police. I guess they would have to visit the forecourt as part of their enquiries. They may get a different answer in terms of the video (i.e. the attendants may be instructed to say the cameras are not on so that Sainsbury's don't get dragged into what they deem as a third party incident, or they may simply be reluctant to hand over tapes that they think they will never get back).
Might be worth gettting your 'crime' number if you get one and then quote this in the letter you write to Sainsbury's, I guess to the Customer Service Manager.
Hope you get the scumbag and that your good lady is ok and not too beat up.
