Summons was sent to accused for offence u/s138 N.I.ACT through Speed Post with AD but the tracking report shows Item Delivery Confirmed at Kolkata GPO and "Item Returned-Addressee Moved". Earlier when the demand notice was served at this address, the same was returned with endorsement "DOOR LOCKED". In such a case please specify whether service of summons will be deemed to be a good service or not and How to proceed in court?
