I have asked about this problem by opening a support ticket already. but nobody is there to help properly. The staff just tells how to enable notifications from my account, And I did the same several times. But I still do not receive the notification emails of payments and order status. Now I just received an order when I was offline and after several hours, I do not know the order status therefore I cannot process the order at my end nor and provide the service to the customer.

I checked the spam box already, and this is something wrong with my account.
