Nimble group is Full of n******** ,

I been receiving calls from Nimble saying I haven't been paying for my Russell's account and I have over a year paying for my account and now it's on credit report, please can I have it removed coz this past 2moths it's showing missed payments but debit order for my russels account already went through for this month, it's frustrating for someone to call n now u have to provide information about something I know I'm paying
