Hi there brooke,
I had been discharged for 4 years, before I embarked on the task of cleaning up the files.
I too had applied for various account upgrades, the coop even phoning and sending me letters, telling me that I was eligible for an upgrade, to be then turned down, because my files were in dissaray.
I started cleaning them up in September, and it is still ongoing now. I have to report the RBS to the ICO, as they just have not responded to my request.
With most of the debts marked as settled or partial settled, I then went back to the coop, a couple of weeks ago, and still got turned down, even though I have run the account perfectly. If there is bankruptcy on your file, then I reckon you don't have a cat in hells chance.
Good luck to you in cleaning your files
