Hello Md. Anowar Hossan Mizan,
Welcome to Microsoft Q&A forum.
It seems that you need help from VS subscription/license/account/sales team. I would suggest you can go here Visual Studio Subscription Support. Click "Account, Subscription and Billing Support", select country/region and try Live Chat or directly using the provided phone number to call for VS subscription support.
Best Regards,
Dou
