Nationwide Duct Cleaning

Terrible Terrible Terrible. We bought a WagJag coupon, so we are stuck with using Nationwide Duct Cleaning. They schedule a day, then don't give you a time until late the day before. I've wasted 2 Saturdays trying to get service from them. The first Saturday, they called to cancel when they were supposed to be there. Today, they showed up 2 hours early at 8:00am, which I can't do, because I have tenants in my basement, so they just left. I have been waiting for a callback for 2 hours.... I will never attempt to call them again.
