Not sure who's fault my problem was created by,but for whatever reason the barrier on returning would not open,pressed the help button and talked with a member of staff who told me I had to pay extra as my stay had overrun when I explained I had payed for late return cover still existed I had to pay extra,when she checked my booking she gave me the complete wrong numberplate,eventually after telling her I would not be paying any extra she said she would let me out,her tone was as if she was actually doing me a favour .such a shame as have used many times before without any issues.
