Sorry to hear of your experience - it's horrible to suffer like that.
This link may help you gt a refund of any overnight costs - from what you write, I can't see why you were not given HOTAC.
The relevant text from easyJet's T&Cs are....

2. If your flight is cancelled as a result of extraordinary circumstances
If your flight is cancelled as a result of extraordinary circumstances which could not have been avoided even though we took all reasonable steps , including but not limited to:
* Air Traffic Control
* Weather
* Civil unrest
* Terrorist alerts and Security alerts
* Strike Action
* Unexpected flight safety shortcomings
easyJet will not compensate you further other than providing you with one of the following options (“Re-routing and Reimbursement Options”):
You will be offered:
1. Re-routing to your final destination at the earliest opportunity; or
2. Re-routing to your final destination at later date at your convenience and subject to availability; or
3. A refund of the fare paid for the journey not made. Additionally, where relevant, we will offer a return flight to the first point of departure at the earliest available time.
In addition, you will be offered free of charge two telephone calls, or telex or fax messages or emails.
Where you choose to be re-routed at the earliest opportunity:
1. You will be provided with meals and refreshments (or vouchers) in a reasonable relation to your waiting time; and
2. If an overnight stay is required because the reasonably expected time of departure is at least the day after the time of departure previously announced, easyJet shall offer you hotel accommodation and transport between the airport and the hotel (within reason).
