Why didn’t I receive any credit bureau letters this round (Round 4)?

This is intentional and by design.

In Round 4, the Smart Credit Algorithm™ strategically has the credit bureaus sit this round out. Instead of sending letters to the bureaus, this round focuses exclusively on the data furnisher — meaning the collection agency and/or original creditor reporting the account.

At this stage, your goal is to work directly with the data furnisher and place pressure where it matters most.
