If something is really works well. We must appreciate.
My daughter placed an order by mistake yesterday night.
I immediately sent a WhatsApp mgs *******200) and requested them to cancel the order.
Today morning they sent me a mgs. That they will cancel my order and inform me in sms.
It did not take even 24 hours. My order was canceled and got a sms.
Whoever handles whats app... communicated well.
