credit score-dmc

Just want to complain about DMC that does not help people over the phone we have to email from one person to the next and you get nowhere,my boyfriend has an account by hifi corp and it goes off every month on a debit order but when you log in on clearscore it shows every month missed payments and now reflects bad on his Credit bureau. All we want is for them to clear it off the system so that he has no bad Credit information. We wanted to do things yesterday on his name but was declined due to the account with missed payments but it gets paid every month. Can someone just assist to have it cleared of system so his name is clear so that nothing reflects on Credit bureau. All emails have been sent to them with screenshots so we need assistance asap. Thank you.
