Once again (I will NEVER use your service again as i thought before it was a one off), we could not get out at the barrier and were ordered to pay £160 to leave, having pre-paid. Fine, i pressed the button and explained to a surly and absolutely unhelpful woman the problem and she insisted that without the booking reference (which was in the bottom of my suitcase) we would have to pay. Last time (and as i say i thought it was a one off) we simply gave our vehicle registration number. She refused to accept it. I refused to empty my suitcase. In the end she did accept it (and it took about 5 seconds for her to find the booking so she was clearly not telling the truth when she said it would be impossible), and let us out. We had a lovely relaxing holiday, but the stress when we had to argue out way out of the car park was unbelievable. No-one should have to be put in such a position. in fact looking at other reviews I note that people have unfortunately paid the money demanded at the barrier. I would suggest this is unlawful. Most of them appear to have to wait for a few weeks to get a refund. I think this is a scam frankly. some people may not reclaim the money. It is now over two weeks since this happened and I am still angry about it. Anna Bailey.
