DO PARK AT RICHMOND STATION NCP in LONDON, no staff to help only call button on exit. People are unable to park up as full, after 20 mins of going round and round, unable to park then gave up, they went to the barrier, they refused to let anyone out unless they paid, even though they did not PARK UP. Therefore caused a back log of traffic backing up to level one. People refused to pay , but then had no choice and was FORCED TO PAY This is disgusting, the barriers should have been put up for them, they say registration is taken going in , so they can see people did not PARK UP, was here so called cameras watching, I don't think so. They should have let them let out , instead we had to suffer and be late for our events .
