Miserable, I paid 280 euros for an internal flight with insurance included at a company that no one had heard of, Colonnade, I checked the flight data and I found out that my flight was actually more than two weeks from the date I checked (the net is full of such complaints),
they don't have a call center where to go, so I had to buy other tickets at the airport for 320 euros.
Finally, I arrived at the insurance company that sent me a letter that did not want to be recommended, that the insured amount does not cover the return of money in such cases and to continue my work.
I do not recommend it in any form, I hope that those from OPC do their job.
Below are the conditions for returning the money from the esky site.

"Careful!
To avoid unpleasant situations that may interfere with the smooth running of the flight, take out travel insurance: this covers the risk of canceling or shortening the trip, and the amount reimbursed can reach up to 1,500 euros. Travel insurance can be taken out on our website within 48 hours of booking the flight. "
