I bought a ticket from Siebnen Schorrenstrasse to ZH airport on Monday morning, but the driver misunderstood my order, and charged me for 2 way ticket, while I ordered 1 way as I am returning back on Sun. the total cost was 26.60 and I paid by Twint. Could you return me back 50%? he promises to report this. thanks. could you reach me via mail, it is impossible to contact you.
