Mango airlines inefficient as usual

We booked online a month ago but made a mistake with the dates. Before 24 hours were over, I had successfully changed the dates and was told that the ONLY outstanding amount I needed to pay was 1400 and that I could pay at the airport. Which I did.

For the return flight from PE, I was told that I had to pay an additional outstanding amount and instead of your front desk staff assisting, they sat behind a phone staring at a computer repeating the same ******* to me.

We had 30 minutes till boarding and they now wanted to listen to an hour he long recording of my phone call with the original staff member when I changed the dates.

Totally inefficient.
