Nible group makes people pay one debt twice

Nible group buys accounts from Getbucks, and they will place that account twice on people's credit report, They will collect/debit twice for the same account every month, Both these companies are collecting from me twice for the same debt and it is appearing twice on my credit report and that is affecting my credit score. I have emailed them several times, asking them to remove the listing on my profile but they do not want.
