Hi rak,
Based on current situation, I would like to suggest you contact the Billing Support. You can select your country or region and get the Billing Support phone number via http://virtualchat.support.microsoft.com/client/default.aspx?siteid=32ECF580-B446-44E5-8B4D-25F0AFE07779&uiscope=en_US&scope=billing&query=Billing%20Support%20phone%20number
Thanks,
Allen Zhang
