I was contacted by a collection agency about an "unknown debt" that they say occured more than 20 years ago. This debt has never appeared on any of my credit reports to date. Nor, do I rememeber back 20 years ago about this credit card debt/default. They are requesting that I pay $2,000+ amount, and an add'l $4600 interest, totaling close to $7000. They will not give me any information regarding this proposed crdeit card, only that it initiated with an account First Omni.
