I am unable to book the surf flat 1000 option from 'Mein Congstar'. It says 'Aufgrund Ihrer bereits gebuchten Optionen in der Optionsgruppe Surfen, können keine weiteren Optionen zugebucht werden.'
Thanks for the reply. I got an email today saying that my old option was active till yesterday 09.06.2013. It also shows 'gekundigt' alongside my old plan on 'myCongstar' portal.
at the moment we seem to have troubles with the booking process. Please visit us at the support-chat you can see at the top of the page. My colleagues can book the option for you.
