Once you booked and paid you can no longer expect customer service after sales. They will reply to your email with a bot and promise to get back to you within 24 hours but you will wait for the rest of your life for nothing. 20+ emails I've sent none of them get an answer. I ended up contacting Singapore Airlines Head Office to escalate the issue and report them and that's how I got my refund from them. Please do not book from this site and don't waste your money and time.
Dear Vincent,
Request you help me with your Rehlat Booking details so that I can check and resolve your issues to the best of my ability.
Regards
Customer Delight Team
