Recent Findings of this LVNV

Thank You and October Blessings to you this month also for what you are doing here. I recently found this company on my credit report. Disputed with Equifax and they emailed me a reply that this is my debt. I had Bankruptcy discharge in 2001, started learning early in life...lol, and just recently started trying to tackle staying on top of things. I should only have my student loan info on there and was shocked to find this. I attempted calling the company at that 1183 line to find they are closed on Fridays?! A business attempting to get monies?! Anyway, the address from them on my end reflects: PO Box 10584, Greenville, SC 29603-0584 with that 1183 line. I have never resided in SC and have lived in TX, OK, CA, LA, TN, and AR. Is there another way I can find out where the so called original reporting agency is from and what it is in regards to? It says . Most of the 2006 charges that 'were' appearing were removed since I have been in the clear since my bankruptcy so at a total loss as to why this is not being removed or what it is linked to....
Best Regards,
