Due to measures to control the spread of the coronavirus, the event has been cancelled or moved to another date. You received a message about this a few weeks ago by e-mail. In that message we informed you about the opportunity to request a refund within 4 weeks. Within the agreements of the voucher scheme that is supported by the Ministry of Education, Culture and Science and ACM, this is seen as a "reasonable period". As soon as this period has expired, we will initiate the voucher application. Unfortunately, this request cannot be reversed after the expired period.
