Settled account in advance, Bradlows failed to notify Experian, leading to my credit score falling - Consumer Complaint for Bradlows - Head Office

My wife purchased a few items from Bradlows phoenix, we settle the account in advance and in September this year, however bradlows failed to notify any of the credit bureau, causing my wife's credit score to drop, as it reflects that we are not making payment, which is now affecting us from taking a home loan, we had no assistance from the phoenix branch, and we called the head office.
