Refund of money paid for purchasing a beauty salon that never happened

Hi,

We are planning to buy a beauty salon and we have given the owner a deposit of AED 20k. After a week he asked for another AED 50k as he has dues that need to be settled with the landlord.

He gave us a cheque for AED 50k which bounced because the account has been closed a long time back as per the bank. It’s been 49 days and the transfer is not done yet. Can we file a civil case and ask for moral damage as we lost a lot of money since the business is not operating yet? Can we still get our AED 70k that we had given to him?
