Why did TU "delete" complete TL’s and I only disputed the balance owed?

Hello FICO Family,

My question and confusion comes from TU. I had two CC’s that was “closed by grantor”. One was GEMB/Lowes and the other was AMEX Clear Card. The GEMB/Lowes was reporting a $882 balance and AMEX $406 balance. I had PIF both cards and wanted to decrease my balances on my CR by that $1,300 odd dollars. So I disputed the balance owed with TU and EQ.

The very next day TU emails stating the dispute process had been completed and here is the results. Both accounts were showing “DELETED”. Why would they do that I had a excellent history with both CC’s and I didn’t want the entire TL removed just a $0 balance to report. What action can I take to right this wrong. The dispute is still in process with EQ.
