Someone in your situation may wish to consider a lawsuit against them. 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.
Here, this may be for negligence, breach of contract, as well as a violation of the Texas Deceptive Trade Practices Act (see HERE).
In such a lawsuit, the Court may award damages of what was paid to them, what it would cost to fix it elsewhere, and legal/attorney fees plus punitive damages. You may wish to talk to counsel face to face about such a claim. Some attorneys may even take this on a contingency, meaning they do not get paid until/unless you do.
