Dear Sir or Madame,

Although the airline Swiss agreed to return my taxes and fees for the missed flight to Belgrade (I checked this via the phone)

TICKET:724-8959295284, Buchungscode:3GRJFU

you never responed to my emails and lately also stopped providing support on your hotline. This is unprofessional and unacceptable.

Please reply to my complaint in order not to lose even more customers.

Best regards
