I believe my parents have been victims of fraud. They had a general contractor fix their roof and the GC brought a subcontractor to do the roofing job. My parents paid the GC when the roofing finished but the GC did not provide correct documents such as a formal estimate nor invoice and had been putting off providing them the documents. About a month later, the SC came to the house threatening to tear the roof off if they are not paid. My parents and SC had been calling to resolve the issue but GC keeps making excuses and dodging. The SC made threats to file a lien against the house. Before the work was done, GC paid them partially in cash but did not pay the rest afterwards.
