Bigbasket.com — non delivery and deny to grant refund

Order id :[protected]

Hi, i was chasing bigbasket every 2 hours on the day delivery was supposed to happen i. E. 15 april.

I also followed up thrice on 16th.

I also followed up thrice on 17th.

Now on 18 april, they did not grant me refund, saying that the order is past 48 hours. It was deliberately done to earn money using unenthical way. Please reply.
