Trouble w/ Acropolis E-Ticket Site?

For several days it seems that there are issues with the website's electronic ticketing service.
Some European banks refuse ticket payment transactions for security reasons.

This could be the reason why the booking process is temporarily unavailable.

Thank you JoLui!!

I was fearful that we had missed the window to purchase tickets for our July visit, LOL!

Ticket purchase is now operational on hhticket.gr

trying to purchase eticket online and Hellenic Heritage site is not taking payments. Any word on when it will be up and running to take payments again? Thank you

I just bought tickets

On French travel forums there are the same reports about problems with online payments.

For someone, using a German online bank (N26) seemed to work. (!)

I am still receiving unsuccessful payment response ordering from the US. please advise

bank card best to use for purchasing tickets
