Crockery.india instagram seller is not responding

I had placed an order in “crockery.india” on 7th May, 20223, for a tea cup saucer set of 6. I payed 999 rupees through online payment and was said that I’ll receive my items within 5-7 days. I contacted them after 10 days as I had not received my item. They said that I’ll receive my item tomorrow. I waited for for few more days and when I messaged them regarding my order, they are not responding to my messages. They are not responding no matter what I message. Its been a lot of stress. Its been 3 weeks since I had ordered and and I did not receive anything nor are they refunding my money back. There is no response from them. Please help me out.
