Best Arc Fault Circuit in Charlotte NC

The service was fine, but the cost was ridiculous. The job took 20 minutes. The tech walked around a 400 sqft space testing outlets, removed the covers from the electric panel and meter, determined I wasn't getting enough voltage, and told me to call the power company. I was told $69, he ran my card, then sent the invoice and receipt. My first glance at the invoice I just paid showed $301 and change. Ridiculous
