BloomsVilla — Order not delivered BV2260389

I placed an order on 14th February because it explicitly stated that it would be delivered on the same day. At the time of writing, it is an hour away from 16th. I still have not received my order, nor have I been informed of any potential delay. Customer support is unreachable. Emails are ignored, so is the "instant" chats on their website.
I added an item to my cart, so a person from their team called me to ask if I wanted help with the checkout. I, then stated my concern and she promised delivery today. She then hung up the call. I managed to chat with a so-called 'Mamta' from their chat team, and she assured me I would get the delivery in 30 minutes. It is now 5 hours since that chat.
Turns out, I'm one among hundreds more facing this. I managed to talk to others facing the same issues with Bloomsvilla and we are surprised this is still allowed to happen. It's now 2 days past the occasion and the whole purpose is lost. I would like a refund.
