Leave & license agreement

I am a owner and recently have done leave and license agreement with licencee (tenant) for 11 months ( from 01.05.2018 to 31.03.2019) thru online procedure thru authorised service providers (ASP) of govt. of maharashtra ( stamp duty dept). the agreement was done on 29.04.18 (sunday ) online & ASP paid registration charges and stamp duty online. tenant had given me the security deposit cheque & 10 rent cheques ( post dated) . First rent rcvd in cash as due to bank holidays cheques were to be deposited in the bank on 02.05.2018. According to ASP registration was in process & final copies to get on 04 th or 5th of May 2018.flat keys were handed over on 30.04.2018. But suddenly tenant made stop payment of sec. deposit chq & informed me thru sms at night . He didn't inform or discuss anything about cancellation. It was sudden. and started asking refund of cash ie first rent. I requested ASP to stop the process & he said he will do. Now the question is actually there is no agreement registered and deal is broken by tenant & even he asking refund of cash ie. first rent. because of this broken deal i have missed other clients also & it is loss incurred. Owner has any protection in this case ??????? how this tenant to be penalised ??? if the agreement has registered what is the cancellation procedure........
