Stayclassy.in — didn't received the order

Address:

Hoshiarpur, Punjab, 146001

I had ordered one mobile cover for vivo y93 and the payment has already been done.
Today, I received a message that my order has been successfully delivered.
But actually i hadn't received my order.
If my order has not been delivered to me, then to whom it has been delivered.
I tried to contact at the helpline numbers provided at the site, but no response was given.
I want my order.
So, please kindly look into this matter.
