Mango Airlines is dreadful. NO customer service.

I have 2 return bookings Dbn CTown. I have just been sent an SMS to say that we are no longer on our return flight, but have been booked on a later return CT DBN flight. I have tried 6 of the call lines to Mango, but they all just shut me off and block the call. 1) Why not communicate with passengers 2) Why not open your call centres so we can talk to you. These return flights do not suit us and so I want to change airlines but Mango are totally unavailable.

This must be the worst customer service ever, BUT mango know they have that name anyway
