Hi, I ordered 5 Point-to-point tickets from Tirano to St.Moritz. However, I just found that I typed wrong surname for one ticket (it should be Jian but I misspelled to Jiang) because another friend’s surname is Jiang. Will this be a problem or is there any way I can change it? I tried to refund the whole order, however, it keeps say “Captcha could not be verified.”. Then I am not able to finish the form. Thanks.
