Go through the toll for cars/cash/bank card (your own) only… pay the going rate for a car that way, £6 summat!! Or just go through a manned one, tell 'em you’ve got no tag and fill the form in…company name etc etc. The thing I don’t like about using my own card when the TAG was busted is you present it to the reader and that’s it…it doesn’t ask for your PIN…so if our TAG has ‘low credit’, I choose to spend 1 minute filling the form!
