I am over £1,000 out of pocket!
This is a great airline to fly with. However I cannot give more 1 star given the recent customer service experience. Basically I had a two leg Premium Economy ticket (Melbourne to London via Singapore). I asked to cancel the second segment and I was told that after deducting a cancellation fee they would get a refund of £1221. Then I go to the website to cancel but somehow cancelled the entire booking for the same refund amount. Two hours later i realize the mistake. I call their customer service (and even escalate to a manager, Mr. Vino) to ask to rectify as it literally didn't change anything for Singapore Air but they keep repeating that there is nothing they can do and I have to rebook the flight costing me over £1000. I might have been the one to make the mistake here but the total luck of understanding and unwillingness to resolve a very costly problem (for a genuine simple error) made this the worst customer experience ever. Cannot be more disappointed than this!
