I have not yet run into either TMT or Big Sky. New debt collection companies are constantly being formed.
Did you call U.S. Bank in response to a call or letter asking you to pay? If your concern is about whether the collector is following the law, I suggest you speak with a local consumer rights attorney. You can look for one at www.naca.net.

The information ("the answer") provided above is for general information and educational purposes only. The answer should not be taken as legal advice for any individual case or situation.

My firm will ask you to sign a written contract prior to the commencement of representation in any attorney-client relationship. Please contact 770 427 5600 or 404 373 1970, if you wish to discuss your situation further. Skaar & Feagle, LLP accepts select consumer rights cases. These cases include, but are not limited to, cases of abusive and unlawful collection activity, debt defense, credit reporting of false or obsolete (old) information, high interest lenders (title pawns, payday loans), debt management plans, and fraud or unfair practices in the sale and financing of automobiles.
I have never heard of them, and technically, this is not a legal question.
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.
