Dear Newsha,
The only reason your order gets canceled is when your payment was not received within the given time limit or it has not been confirmed yet by the blockchain.
I helped you very quickly through PM. Please be informed that our helpdesk is still overloaded, even with 10 new employees.
Thank you for understanding.
