- There is no payment machine in this car park, so you need to have the Paybyphone app. As you are underground you cannot access the internet and even, once you are outside, it is very difficult to get any signal. It all becomes very stressful, it took me ages to get enough signal to finally pay. What they don't tell you, is that they record you arriving by ANPR and start your parking time from that moment, so if you leave it to the last minute to leave when you think your time is up, you are already well over your allotted time. I too have been fined by this unscrupulous carpark. Never again.
