Credit file not updated - Lowell, BW Legal

Hi all!

I’ve been working hard to get debt free and doing well. Payment arrangements in place with Lowell and BW Legal for old debts which I’ve never missed a payment on.

As a few of these are close to being done with I thought I’d check my full credit report. Amazed and horrified to discover it says I’ve missed all payments on these accounts since 2017 when I set up the arrangements.... I quickly put in several disputes and have emailed Lowell and BW but is this likely to work? I have proof of all payments via the Lowell app and my bank statements.

Is this unusual? I’m quite annoyed to be honest... I thought my crappy score was down to still having these arrangements ongoing but evidently it’s also to do with them being listed as missed payments!
