Well, what info did they update? For a debt discharged in BK the creditor can only report it as $0 balance and "Included in Bankruptcy". If payments were late prior to filing of BK they can report those late payments, but they can't claim any late payments after filing BK becuase they were prohibited by federal law from making any attempt to collect the debt.
In my 2010 BK I had a couple creditors who reported 60-90 day lates and then Charge off after I filed. I disputed those with the CRA as an attempt to collect a debt after filing BK, and they were promptly removed.
If you have the credit reports after DC and no lates were showing and all of a sudden lates were placed on your reports. This is a violation of the BK laws. No negative information can be placed on your reports after filing. Take the copies to your lawyer. He can file an injunction against the creditor and they can be fined for $1000 plus court cost and your lawyer fees in your favor.
Even more violations. I recommend as I said earlier. Take copies to your lawyer. And go from there. I'd say dispute it. but you know how CRA's are with disputes. They'll could screw it up more. The law is on your side now. Good Luck!
