Ryanair problems?? Help

[Lunalunamama]

Hiya,
Not sure if anyone can help but I feel like tearing my hair out how stressful it is to book a family holiday.

Ryanair won't accept any of my cards I've tried 3 different cards, private browser even though they accepted my money for deposit. I am now trying to book 10kg for the flight and it keeps saying payment error ( even though I have the money in account) Called Ryanair and they said it should work but nothing seems to be working...
Has this happened to anyone what was the solution?... Thanks

Are you using the same card you booked your flight with?

Yeah same card as the booking but says theres an error not sure what's happened

Try Paypal or Apple/Google Pay?

You're not doing the stupid thing I did once when I was entering the expiry date wrong. My card said expires September 2025, but for reasons unknown, I was selecting 10/2025 on the payment screen so of course it was failing as the details didn't match. It was ages before I realised that it was because September is the ninth month of the year. Doh!

I tried booking flights with Ryanair earlier this week and got card declined. I rang my bank and they said it was probably that Ryanair hadn't yet set up the security factor authentication wotsit that you get increasingly asked for when paying online.
I used my other bank card and it went straight through though!
