If I could score 0 I would. I struggled to make payment for congestion after trying multiple times etc I managed to pay the following day. Still stating I pay £15. It was not made clear that the charge went up to £17.50 as it was outside of 24hrs time frame even though I put my registration number in. You’d like to think in a day and age where everything is online and machine oriented it would have calculated that in-fact the due payment would have been £17.50. But NO! I then have a letter through to say I need to now pay £90. So I called up and actually spoke to someone (of course they can speak to you when taking money for a fine) and they explained and was very helpful I have to say. However. They explained to me that I have to pay the £90 and I can’t just pay the £2.50 extra. And on top you don’t get your £15 back which you innocently paid. Honestly talk about thieving. Feel a bit mugged off paying £105 to drive through a patch of tarmac in London.
