EDIT: TL;DR - According to the TOS, ZOS doesn't owe you anything
This is straight from the Terms of Service that you all agreed to when creating an account to play this game:
ZeniMax does not guarantee that any Services will be available at all times, in all countries and/or all geographic locations, at any given time, or that ZeniMax will continue to offer any particular Services for any particular length of time. Except as prohibited by applicable law and subject to the Statutory Obligations (as defined in Section 1), ZeniMax reserves the right to change and update Content without notice to You. ZeniMax also reserves the right to refuse Your request(s) to acquire Content, and to limit or block any request to acquire Content, including, but not limited to, Downloadable Content and Game Mods, for any reason.
ZeniMax may patch, update, or modify a Service at any time with or without notice to You. Notwithstanding the foregoing, ZeniMax has no obligation to make available any patches, updates or modifications or correct any errors or defects in the Services. ZeniMax makes no guarantees about the persistence or availability of any user names or other personas at any time and assumes no liability for lost or deleted Account data. Except as prohibited by applicable law and subject to the Statutory Obligations (as defined in Section 1), You agree that ZeniMax will not be liable for any interruption of the Services, delay or failure to perform, any loss of Content (including, but not limited to, UGC, Game Mods and Downloadable Content), and/or Account data (including, but not limited to, Character data) resulting from any causes whatsoever. ZeniMax reserves the right to offer new Services, change and/or discontinue certain Services at any time in its sole discretion.
Except as prohibited by applicable law and subject to the Statutory Obligations (as defined in Section 1), ZeniMax may restrict, suspend, or terminate Your access to some or any Services at any time. Should ZeniMax make a material change to the Services, it will provide You notice within the time period specified when You joined the particular Service, or if no time period for notice of material changes was specified, then within thirty (30) days of the date such notice is either (at ZeniMax's discretion) provided to You via email or is posted on the applicable product or ZeniMax Service or on Your "My Account" section.
In response to a violation of these Terms of Service, ZeniMax may issue You a warning, suspend or restrict certain features of Your Account (including, but not limited to, user names), selectively modify or remove or revoke Downloadable Content at an Account and/or device level, immediately terminate any and all Accounts that You have established and/or temporarily or permanently ban Your Account, device, and/or machine from accessing all or certain Services.
ZeniMax may terminate Your access to and/or use of the Services (i) for violating these Terms of Service, (ii) if ZeniMax, in its sole discretion, deems that Your information is untrue, inaccurate, not complete or incomplete; (iii) if Your use of such Services infringes on or is suspected of infringing on another's rights or any intellectual property; (iv) if You or Your Account reflects inappropriate Content and/or violates these Terms of Service. Any and all Content (including, but not limited to, Software, Content, and Downloadable Content) will be considered forfeit immediately in the event of any cancellation, closure, or termination of Your Account by ZeniMax.
If ZeniMax terminates an Account, it may terminate other Accounts that share the same characteristics, such as the name on the Account, email address, mailing address, Internet Protocol address, or credit card number or other Payment Method. ZeniMax reserves the right to use any means necessary and permitted under applicable law to identify and terminate Accounts.
You acknowledge that in such circumstances, ZeniMax is not required to provide You notice before taking action to restrict, suspend or terminate Your access to or use of Services, and/or Your Account. If ZeniMax terminates Your Account, You may not use any Service again without ZeniMax's express written permission. ZeniMax reserves the right to refuse to keep Accounts for, and provide Services to, any individual. You may not allow individuals whose Accounts have been terminated by ZeniMax to use Your Account.
If Your Account, or a particular subscription or membership for a Service associated with Your Account, is terminated or suspended and/or if any Downloadable Content is selectively removed, revoked or garnished from Your Account and/or if Your device is temporarily or permanently banned from accessing some or all of the Services, no refund will be granted, no Downloadable Content will be credited to You or converted to cash or other forms of reimbursement, and You will have no further access to Your Account or Downloadable Content associated with Your Account or the particular Service except where any action has been taken against Your Account or device in error and subject to the Statutory Obligations (as defined in Section 1). If You believe that any action has been taken against Your Account or device in error, please contact Customer Services at support.bethsoft.com.
