Horrible Experience

I had a flight booked with Mango Airlines on Saturday 2 February 2016 at 18h20. Our flight was then delayed 15 minutes boarding time with NO proper explanation. My flight was delayed 2 hours 10 minutes. Now my flight was going to be 20h30. Without any notice we looked at the flight schedule and noticed that our flight was going to be a further 50 minutes delayed. The Mango staff were not certain not could they give us passengers a confirmed answer as to why the flight was further delayed. When we boarded the plane e only to hear the real reason the plane was delayed and this was from the pilot. Our flight was going to be cancelled-Mango Airlines can question their Captain Pilot as to why our flight was over 3 hours delayed. I find this ********* business practice. We pay you for a service, can we further support your airline Business.
