Big Bazaar / Futurebazaar / Future Retail / Hometown — item not delivered from big bazar claiming delivered

Address: Durgapur City Centre, 713216

I shopped from Big Bazar, City Centre, Durgapur 713216 on 05.06.2019. Few grossery heavy items near amount of RS.3000 was given them to deliver to my home. But today on 7the June I got a message from them Challan Number 964117 has been dispatched and will be delivered today, after that messege again a message came in between 15 Minuits the Challan number 964117 has been delivered successfully. First of all the items were really needed to deliver to my home because of my old parents and there is no other way to shop again. Now this type of message increased my blood pressure to the peak, after checking that text message I tried all the way to contact Big Bazars customer service but their service are not open. Tell me what should I do now??
