When I try to check my account on the internet it’s saying my account is disable why
Do you still have services (I am thinking...no, due to your title)?
If yes, this could be your account going through the normal renewal process. The SELF SERVE account can say "expired" or "suspended" on the day of or before your plan is due to renew. So if this is the case, ignore these messages on your SELF SERVE account.
If you have no services, and it is past your renewal, maybe your autopay failed?
Add Funds to your Plan Amount through SELF SERVE (or by calling 611 if you have a card registered)
