Inkgrid — order id # 280987- product not delivered

Address:

Gurgaon, Haryana, 122017

My order id is 280987. I’ve ordered 3+2 sofa set from inkgrid on 30-oct-2018 which is still not delivered yet.
We emailed inkgrid support department and also called them several times. I’ve tried many times to contact them about the status but their is no response from their side. And once or twice they replied and confirmed that the product will be delivered within that particular week but never received any product or update after that. Today is 44th day since the order was placed. Please help me out. Either they give me refund or deliver the sofa by the end of this week.
