My friend and I reserved Flixbus return tickets in November **** from Vienna to Amsterdam for April ****. Little did we know that a pandemic with numerous restrictions was ahead of us. We cancelled our reservation in March, and got a voucher valid for * year, which will expire in * days. *There is still a lot of uncertanity in travelling, crossing borders and restrictions change on a daily basis. We don't want to lose our money, but we don't know what to do. Unfortunately, I am aware that a monetary refund is probably off the table. Therefore, I'm looking for a chance to prolong the validity of the voucher so it can be used in safer times - or at least at times when the Flixbus company has buses travelling between said destinations, because as of today there isn't any bus available between Vienna and Amsterdam not for next week, not for the summer or any time so I cannot use my voucher to reserve tickets for summer or next year (Unless it is between random destinations like London and Paris.) *Thanks in advance, Orsii
