In late February booked April flights.
Got an e-mail from EasyJet 16 March telling me that flights had been canceled, and offering to refund.
Went on line 19 March and asked (by clicking buttons, not by talking to anyone) for a refund. Seemed to work, as I got an e-mail saying that I would be reimbursed within seven (7) business days.
With generous counting, that would have been by 31 March (at the latest). But did not get any reimbursement. So, after reading this thread, on Saturday I asked for charge back with Chase (had booked with Chase Hyatt Visa). They (Chase) immediately responded that a provisional charge back would be issues and, indeed, this morning, Chase credited the money back to my account.
Will now wait to see what EasyJet does, but I do have the e-mail from EasyJet promising the reimbursement, so I'd like to think that I shall be fighting this battle while holding the high ground.
