DMC BAD COMPANY

I was mislead into sighning a contract with DMC . They HAVE BEEN DEBITING MY ACCOUNT FOR THE PAST 3 YEARS WITHOUT FAIL . Yet they still list me as a slow payer and flag me for missed payments since 2017 without informing me that there is an oustanding balance on the account . After struggling with them for years I FINALLY MANAGE TO PAY THE ACCOUNT UP IN FULL ON THE 19 SEPTEMBER 2020 . DMC ADVISED THAT THIS WILL BE REMOVED FROM MY CREDIT REPORT ON THE 05 NOVEMBER 2020 . IT IS THE 16 NOVEMBER YET NOTHING HAS BEEN DONE AND DMC IS STILL REFLECTING BADLY ON MY REPORT EVENTHOUGH I EMAILED THEM THE CREDIT REPORT AS PER THEIR REQUEST . I WAS DECLINED BY THE BANKS FOR A HOME LOAN DUE TO THIS DMC ACCOUNT THAT HAS BEEN PAID UP IN FULL AND I HAVE THE SETTLEMENT LETTER WICH DOESNT HELP . THIS IS ILEAGLE . CAN SOMEONE PLEASE ASSIST TO GETTING THIS MATTER RESOLVED
