Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Illinois

My Barclaycard account was closed, but went to collections. The collections company DID NOT place the account on my credit report, because I settled it in full right away. However, Barclaycard refuses to update my credit report to say that it was settled in full. Even after I disputed it, they have it marked as a charge-off. I need this to be updated, as I am trying to fix my credit.
