Hiding from claims

Easyjet cancelled my flight. They directed me to a claim form on their website to claim back for an alternate flight. When trying to submit this form Captcha times out and the form cannot be submitted. I contacted them on their chatline and they cannot assist. I emailed them to manually put through the claim. They keep on responding with a standard email. Now they have disconnected this email address as well. I have been trying for 9 days now!!!!
