I'm trying to book using paypal (which worked perfectly up to now) but the transfer is denied and I receive this message back:
Oops, we're unable to complete this booking
We were unable to authorize use of your credit card. Please confirm that all the details are correct. You may also contact your bank to confirm that they are not blocking the use of your credit card or you may use an alternate payment method.
I think, if it is possible , as the message told , you could ask your bank. May be there are some details, which you do not know, that you need to add or correct.
