Welcome to Flyertalk Figarocars, I'm sorry to hear about your experiences, but if you want some help to sort it out then this is the right place to get advice.

I have to say that the circumstances of this case seem unusual, in that simply does not compute to the way I have seen easyJet operate on a number of levels. One key aspect relates to the boarding pass, and the evidence seems to suggest that somehow the financial transaction got pulled back by your bank and easyJet cancelled the booking. One good way to get boarding passes from easyJet is to install their app, it's reliable and it also gives a good view into your booking too.

If you definitely did pay, and the bank paid the funds to easyJet by the time of departure, then by all means revert back here and we can take you through the steps relating to EC261 and Involuntary Denied Boarding.
