Confused ex customer

Need explanation why I my account was locked and how did I violate terms and agreement 

No one here can answer that without more information such as what plan did you have, what device were you using, etc.

We understand how important it is to be able to access your account, @Twilson63.

Let's meet in a Direct Message, so we can further review this. Please check your Direct Message Inbox (it's the chat icon next to the bell icon in the upper right corner of the Forums).

We look forward to speaking with you.
