Ringgo charged me for the full 24 hrs, even though we were parked for 1 hr 15 mins and correctly stopped the parking session when we returned to our car. They took over £10 out of my account when the charge should have been £2.70. Apparently they will return the difference in the next few days but only after holding the excess and making money off the interest. An absolute con, this should be illegal. Be warned, also switch off text/email alerts in the app or they will also charge you for each 'helpful' summary and reminder. A huge ripoff, complaints being investigated nationally. Avoid.
