Hi,
Got the below from euro parking services, there are no double lines where I parked, they also left it quite late in sending this, recieved today, as i'd now have only 2 days to pay the lower amount.
There was a sign with just "no parking" facing the driver, and presumably the other sign facing the road has the euro parking warning, didn't read this as I didn't get out of the car just stopped to take a call.
