Biggest pile of sh**e ever! I have to park in a ringo carpark for work, I’ve been parking there using the app for 4 months no problem, then all of a sudden it won’t take my payment and said there’s an error. Tried uninstalling app, deleting and re-adding cards and still getting the error. Phoned my bank, they said there’s nothing wrong with my cards, tried my partners card (who also uses the same bank as me) and his worked! Went onto live chat with ringo, totally useless, all they could tell me was there was a new higher security when paying with some banks and it will eventually be resolved. I asked why my partner’s card works on my app and mine doesn’t and they said “they couldn’t discuss this with me” and I should send an email. I sent an email and after a week, I’ve had no response. They are a money grabbing joke of a company with ZERO customer support and should be shut down.
