I'm trying to book a flight for mid-September next month via the SriLankan Airlines website. However, when I input my payment information, I get an error page saying that there is something wrong. I've tried inputting this information multiple times via multiple browsers and on different computers (using different cards - credit/debit), but no luck! I already emailed the airlines, but I haven't received a response and the telephone numbers they have provided do not seem to work. Any help would be much appreciated - thank you!
