KIWI.com chargeback ?

Hello guys, I have had a stupidity to book a trip via kiwi.

Afterwards it happened that i had to cancel the flight , and its already been like a week since i cancelled flights on their platform, but the progress on their platform is still saying they're processing it (they did not cancel it with airlines for some reason) and on airlines site bookings are still active.

I guess they want to wait until the flight date and then decline refund for "no show reason" or something like that.

How do you think, if I open a chargeback dispute with bank, is it possible to win over this ?

Thank you.
