Dispute or leave alone - Citibank

I have a Gulf State - Citibank derog on all three of my reports.

It's the only item at all on my Equifax report and the DLA is 12/94.

On Experian it is listed under Accounts in Good Standing as Transferred. Under Original Creditor it says SOLD COLLINS FINANCIAL 12/2/99. I still am not sure if Collins sold to Gulf or Gulf sold to Collins. It says:This account will continue on record until 12/2001. There are 2 hard inquiries from Gulf on this report from 12/99 and 10/99. Nothing since.

The TU report that I got from worthknowing.com lists the item as having a Balance date of 7/1/99.

Should I let sleeping dogs lie for now and deal with it after December when it falls off the other 2 reports or should I dispute this with TU?

I have never ever heard from Gulf State on this matter at all. (I know. I'm lucky)

Thanks

 

Thanks George.
