Should i be concern

Rjm must have pulled a copy of your credit report and viewed it. They have reviewed your accounts from the credit report. This is why it is showing on your credit report. A lot of collection agencies often do this.

that being said they need permissable purpose to pull your credit.keep a close eye as RJM is a notorious bottomfeeder.in fact do a search in the bar top right.it will give you insight on them,but again keep a close eye as i wouldn't trust them at all.

When anyone reviews your credit report, it has shown as an inquiry. In your case, your account has been reviewed by Rjm acquisition. That is why it is showing on your credit report. Multiple inquiries on your credit report may create a negative impact on your credit score.

Call them and ask? What past due bills do you owe?

RJM Acquisitions is a debt buyer. They will often repackage debts they purchase and resell them.

The inquiry from them is a "soft pull" and should not have an affect on your credit report or credit score. If you have debts that are unpaid and outstanding it is likely they are performing a skip trace in order to determine the next step they will take in either attempting to collect or resell the account.

If you do not have debts outstanding, or if the inquiry shows as a hard pull (which can affect your credit score - marginally) you should contact RJM in order to learn more detail and take corrective action.
