Khelmart.com — no order updates & all the email id is bouncing

Website:

www.khelmart.com

I placed an order for 1 no badminton shoes and 2 no badminton shorts on 20th of december 2017. During the order placement the payment was deducted and i received an sms confirmation for deduction of payment from bank and then their website got crashed before issuing an order id/order confirmation. But so far they haven't send any confirmation email or sms.

I contacted khelmart and it's been confirmed from their side that the payment is received. But so far i haven't received any confirmation from their side via email/sms.

The order id which they gave me was 200928.
I sent an email mentioned below and all got bounced with this error.

And their user interface and web portal is always crashing.
