Expedia nightmare! Trapped in robot world

[hedgehoggle]

I am having a nightmare experience with Expedia!

I attempted to book some flights last night and their website kept crashing so I gave up and booked elsewhere. This morning I find I have been billed for 1 flight (not even the return I was trying to book! So I'd be stranded anyway) by easyJet. It must have come from Expedia as I wasn't on the easyJet website. However I have NOTHING from Expedia - no confirmation, no itinerary number, nothing. Because I lack all of these details I cannot get past the robots to cancel this useless flight!

Has anyone got any ideas?? I have 24 hours to cancel. I've emailed easyJet and Expedia, but I'm not confident the Expedia email is to the right place. I booked with debit, not credit card, which I sorely regret. My bank (robot) says I need to speak to the merchant.

Oh, to clarify it's a domestic flight that's why it's in UK travel

BE WARNED!!! We already know, but just a reminder…Eadyjet are rip-off artists & shysters. Booked flight, added/PAID FOR hold luggage, decided to swap hold luggage for windsurf bag, couldn’t do it in-app so phoned them. Was told no, there’s no option to swap/refund bag, I have to add/PAY FOR 2nd bag also. Frickn thieves. DONT USE sleazyjet!!! TUI also fly!
