I suggest you now send copies of all correspondence in a formal complaint to the DVLA evidencing their complete disregard for PoFa and the BPA/IPC PPSCoP.
Again please forgive my total dumbness here but:-
1) Is this a formal complaint to the DVLA over Alliance Parking's disregard for PoFa and the BPA/IPC PPSCop, Or DVLA's disregard for giving my info to Alliance Parking.
2) I do not fully understand how PoFa and the BPA/IPC PPSCoP in my case may have been "disregarded", how exactly have they shown this disregard?
3) I cannot find a email address to send this complaint to, is there an email address or will it have to be sent via post.
