I think cuz I changed my plan NOT IN TIME this payment will carry over to January 2019? So do I make another payment right now?
Stop making more payment. Your account is active and calls going to your voicemail. Your account was not provisioned correctly. Try the lost/stolen phone trick to provision your plan feature again.
1. Login to your self-serve account.
2. Report your phone lost/stolen using [Plan and Add-Ons] --> [Lost/Stolen Phone]
4. Wait 5 minutes and login again
5. Report your phone found.
6. Re-start you phone to provision your account again. i.e. enable all features of you plan again.
If this trick failed to get thing working again, you should send a private message to moderator for help. But the wait is about 48 - 72 hours. Good luck.
