No, there is no consumer agency that will take the case for you. For cases like these, you are on your own. Technically you can report to the Attorney General, but the AG only acts if dozens, if not hundreds, complain.
To sue in a state court, one needs to have a "cause of action." There are numerous causes of action, such as "breach of contract," "negligence," "fraud," "unjust enrichment," etc., as well as causes of action rooted in statutory law. Every state has their own although they are very similar to each other in every state because they all stem from the same common law. A pleading in Court needs at least one cause of action, although it is not unusual to have more than one.
Herein, one can sue the company for warranty and TX Deceptive Trade Practices Act, arguably.
When one purchases an item, even if one does not have a specific warranty, it comes with a set of implied warranties. These implied warranties are very ambiguous in law by nature.
An implied warranty of fitness for a particular purpose is a warranty implied by law that if a seller knows or has reason to know of a particular purpose for which some item is being purchased by the buyer, the seller is guaranteeing that the item is fit for that particular purpose. Recognized in Texas under Tex.Bus. & Com.Code Ann. § 2.315.
An implied warranty of merchantability is a warranty implied by law that goods are reasonably fit for the general purpose for which they are sold. Recognized in Texas -under Tex.Bus. & Com.Code Ann. § 2.314.

I would recommend finding an attorney that may be willing to look into the case.
