Bad service

I went to settle my account at truworths Kimberley, 3 march. I requested a paid up letter. After they contacted there accounts department they were informed that the account was handed over to dmc and they could not interfere with accounts handed over. Yet they accepted my payment. After contacting dmc I was informed that the account was handed back to truworths on the 23 January 2023. I returned to the store where I was promised that the manager would get back to me immediately. I have recieved no contact. Your intervention will be appreciated. Contact ***.
