Hi Toseef,
Thanks for reaching out. I know how frustrating it is to be locked out. I'm here to help!
The only way to get your account back is by using the Account Recovery Form: https://account.live.com/acsr. You can submit the form twice every 24 hours, so if you remember more details, give it another shot. For security reasons, Microsoft's recovery is automated, so support can't manually check your identity or bypass the system. Not having your old recovery phone or being in a new place makes it harder, since the system checks your usual devices and locations.
If your request to get your Microsoft account back didn't work, click this link for details: https://support.microsoft.com/office/dc56c3e3-dff0-4ed5-8edb-60290eea6b53
