When I bought my ticket from edreams they had an offer if you sign up for edreams prime membership they offer a special price. For the ticket.
It also wrote specifically that you can cancel your edreams prime membership at any time since after the first month there is a monthly charge OF 9.00 euro
They provided a telephone number to cancel the membership that is is presumably available 24/7.
It is IMPOSSIBLE TO CANCEL MEMBERSHIP.
When you call this number there is a recording and you are NEVER connected to someone so you can cancel membership.
Of course this is intentional so you have to pay for edreams prime membership forever.
EDREAMS does not provide an option for you to cancel prime membership ONLINE.
EDTEAMS are hoping you will eventually give up trying to cancel membership
or that you are so stupid you will not notice they are charging you 9.00 euro every month
for the rest of your life. AVOID THIS COMPANY.
