Kiwi.com complaint: Legal Fraud

kiwi.com committed legal fraud by selling me a product that could not be used. I was leaving New Zealand permanently to return to my native country, the UK, due to the pandemic and purchased tickets with Kiwi.com to fly from Christchurch to Auckland, Auckland to Hong Kong, Hong Kong to Helsinki and Helsinki to Manchester. The first 2 flights were with Air NZ and the second 2 flights were with Finair. I arrived in Auckland and was not permitted onto the flight to Hong Kong. The reason for this was because HongKong had closed their international transfer lounge so since I was using a different airline for my onward travel they would not permit me on the flight to HongKong as there was currently no way they could facilitate my transfer to Helsinki. (I required a single ticket with my onward journey included). The flights went ahead without me and I was forced to pay close to $3000 to book last minute flights home. I received little to no help from Kiwi.com at the time. I have since been requesting a refund for the original flights from Auckland – Hong Kong – Helsinki – Manchester. (1 flight with AirNz and 2 flights with Finair). I am being ignored and fobbed off by kiwi.com who cannot seem to grasp the complaint. They keep telling me the refund process is delayed and they are waiting to hear back from the airlines. I have repeated myself multiple times trying to explain that I am not disputing a flight that was cancelled and that the airlines are not at fault. My issue is that kiwi.com sold me a journey that did not exist. They sold me a product that I could not use. I have transcripts of conversations with various agents who simply repeat irrelevant facts about cancelled flights to me and who are also refusing to escalate my complaint. Another issue I have is that I have explained that my account that I made the payments from no longer exists as I was leaving the country permanently. They are also offering no solution to this and ignoring the issue.
