Surat shopping - Fake parcel from fraud company received

I had not ordered anything and * but received a parcel from Shadow Fax delivery boy saying i have a courier, cash on delivery for a parcel , i assumed my neighbour would have ordered as her mobile number was mentioned with my address and paid the money..at the same moment I received a call from other district from a brother receiving a same parcel of same cost and rubbish stuff received by him too ..within mins I realised the scam, when i called back the executive was giving weird responses...then ignored my calls and when i tried reaching Shadowfax and its management, they are silent...clearly, it looks like a scam and shadow fax is a party to the scam.
