Stayclassy.in — after tracking order, it shows 'pending payment' even after paying full amount.

I placed an order for one plus 3t mobile cover on 28th june. The order number is 1692166. I tracked the order after 2 days, and it said pending payment till even after paying the whole amount via debit card and paytm wallet. It's been a week now and the order status hasn't changed.

I have already contacted your helpline numerous times but no one picked up or the number was switched off.

Hence either give me a full refund or deliver my order asap.
