Old Mortgage company reporting me years after selling house?

I owned a house, financed through GMAC mortgage from 2001 to 2005, when I sold it. Years go by, nothing wrong. As of January this year, they reported me for being delinquent on a single mortgage payment 3 yrs later. I started the process of a home loan app today with another company and they tell me I currently have a mortgage loan, for the exact amount of my old mortgage. I keep tabs on my credit using equifax.com and I had never seen antyhing. Today I check back, and now it shows I have a $130,000 mortgage (amount of my old house) to some comapny I've never heard of. In fact, there seems to be a few names involved - my credit report shows "NetBank" and the person processing my app shows RBMG, and I also saw a Resource Mortgage somewhere too. The only phone number I found is busy all of the time. I googled the address and it leads to south carolina consumer protection agency. All of this is really weird. Anyone seen this before or have any idea what is going on?
