Hi tld2020
You are correct, your question is outside the remit of the forum.
I have read that some claimants who were on furlough may have to repay it due to not being entitled to it. You may want to contact a welfare rights organisation for more specific information.
You can find your local Welfare Rights Organisation to help you with advice by clicking on the link below and putting in your post code, it will then come up with a MAP with a list of agencies.
