Their customer service is an absolute disgrace - a shambles of dishonesty and outright deceit! I can assure you, I will NEVER do booking with them again! It seems they're more interested in hoodwinking customers and pocketing your hard-earned money than in delivering a fair, honest service! Beware - transact with them at your own peril! They've shown their true colors to me, and I won't stand for it! I mistakenly clicked the refund button and the system informed me that this action is irreversible; the refund has been processed and no further reimbursement can be claimed. This experience has been incredibly frustrating, ranking among the most challenging I've faced. In an effort to prevent fellow Koreans from encountering similar issues, I plan to pen a comprehensive article shedding light on the situation.
