cancelled my flight 6 months ago because of covid and stil no way of contacting them. my booking ID and email is not recognized on their website even though they sent me booking confirmation on that same email. its as if they deleted my account so i cant get a refund. a fraud company, never buying from them again. i just want my refund. no one to talk to. even on their social media everyone complaining only getting automated replies telling us to do what is not working.
