"Account is Inactive" - please help!

"Account is Inactive" - please help!

My email address are mohammed.abrar@trunik.com  and info@trunik.com and were working perfectly until a couple of days ago to my surprise since last week i am unable to login to my account. All of a sudden I couldn't connect to my zoho mail through mobile app and couldn't log in to the site. The error message is that my "Account is Inactive". 

I have no idea why it would be considered inactive as it is my primary company's email account and is used extensively every single day.

I couldn't even log in the the support forum with an inactive account. I have created this new account just to get access to the support forums and to ask for urgent support, please.

Thank you in advance.
