Re the footage , serve them with a ‘subject access request’ REQUIRING them to provide the footage , and enclose a cheque for £10 .Thanks for this. At only £2.50 (cheque or POSTAL ORDER - do either still exist!!) and a simple 2 page form, I'll give it a shot then see if I get a response from the offending car owner. Appears Morrisons will not supply video footage, even if it exists, However, the lady who left the details also spoke to my wife and gave her own details plus is happy to witness.
Not holding my breath though!
This is a formal request which they MUST fulfill .
