Local Trailer Brake Controller installers in Huntersville, NC

Actual business was "Hitches-R-Us" which has somehow split from Auto World Lease/Sales. Communication was poor at times and it took effort on my part to establish a firm reservation for work to be done. I had desired to drop car at business and go to medical appointment via Uber. This would give them time to start the install. When I got there (at the designated time), they could not handle. So I took car to medical appt and came back. The install took 6 hours (not the (not the 3-4 predicted). Despite the longer install - the business did not change the quoted price. They stuck with it until complete. And the install was good. Praise to them. But I would not use them again. It is a one-man operation that works outside in their parking lot. Just not a professional garage.
