Follow on from FOI-2535-1718 Thank you for your reply. In terms of question (5) below I understand that you take card details for payment of the Congestion charge accounts. I would therefore like to ask a different question. For the period for six months before and six months after the transfer of systems, can you tell me how many payments of the congestion charge accounts were not collected by the payments system at the first attempt?
