Why at the end of stay and after paying the bill, the guarantee of 1,000 usd requested on arrival is still not refunded 3 months later?

Sorry don't understand

Call them, I got my refund a week later.

Does not speak

ENGLISH PLEASE

I do not know why it happened. We only had a deposit of 100 USD which we spent more than if it was taken if our bill. Did you contact them or even the agent Travek with whom you booked? If you do not, can you claim travel insurance or contact ABTA for advice?
