Thecoverzon — products not delivered on till date

I ordered cover from the https://thecoverzon.com/ and i haven't received then neither have i gotten any update about the order
The status was processing and now i can't even reach the site.

No confirmation mail or bill was shared

The payment was made in advance

I have also tried mailing them on their given customer care email but no response from it too.

An action should be taken against this...
