Two accounts on one decoder

My problems started when one of my three decorders died and becuase i didn't have insurance, i then opted to cancel or deactivate the dead decorder and only have one decorder running from access premium to compact premium. I also deactivated the other one. this meant that i only have one decorder running at compact. this was done propably 40 days ago. when i paid for the account to be restored today, they told me that i have two accounts running. But i told them that i only have one decorder running and not two. How do they running 2 CCCOUNTS OR PERMIUIMS ON ONE DECORDER. I HAVE CANCELLED THE TWO A LONG TIME AGO BUT NO, THEY SAY IN THEIR SYSTEMS, THAT WAS NEVER SCHEDULED. PLEASE HELP CAUSE NOW I OWE THEM ANOTHER FEE. THAT WHICH I DO NOT UNDERSTAND. Looks like i have been paying for both access and compact premiums all along. i am fed up.
