Paid medical account still pursued by Blake Collections after proof and dispute through ER Consultants

I am experiencing ongoing collection contact from Blake Collections regarding a medical account with ER Consulting that has already been paid.

Timeline:

Payment made: 3 Dec 2025

Proof of payment sent to ER Consulting: 3 & 4 Dec 2025

Proof provided in person at Anncron: 22 Dec 2025

Collection contact from Blake Collections began: Feb 2026

Formal dispute sent with proof attached

Matter referred to the Council of Debt (Blake & ER Consulting copied)

Despite this, I have received multiple calls from Blake Collections, including silent/abandoned calls.

This is causing ongoing distress and time disruption despite the account being settled and formally disputed.

I request:

Written confirmation the account is settled

Immediate cessation of all collection contact

Correction of records with ER Consulting and Blake Collections

All proof of payment and correspondence is available.
