My contractor handed my $42,000 pool upgrade to a subcontractor I had already rejected. What can I do?

The homeowner hired Contractor B for a $42,000 pool upgrade after explicitly rejecting Contractor A due to negative reputation concerns. However, Contractor B subcontracted the work to Contractor A, leaving the homeowner concerned about quality and integrity. This situation highlights the risks of trusting subcontractors and the importance of ensuring that chosen contractors maintain control over their projects. The homeowner now faces potential issues with the pool upgrade, raising questions about accountability and the reliability of the contractor network.
