Debt collection — TRANSWORLD SYSTEMS INC (OK)

You told them to stop contacting you, but they keep trying. This is with regard to medical from 2 years ago. These calls from TransWorld Systems , Inc. are unceasing. They have been notified we are on DO NOT Call registry, but they don't care. The ID Code is XXXX. I want this stopped. If they need to contact me they have my address.
