I purchased a flight through this app and after submitting my payment, charges for carry-on and checked baggage were added to my total. I called customer service directly after submitting my payment to correct it and the agent (Allan, who was of Indian descent) was rude and did not want to listen to my side of the story. He said the offer that I selected was no longer available and he could not refund me the amount for the baggage. Then why was the offer still being advertised? After I threatened to write a bad review, he took off the added charges but charged me an extra $10 for the ticket that I purchased. I will never use this app again! The non-refundable clause that is in fine print is a gateway for them to rip you off!
