Once they finally showed up, the customer service and timelyness of work performed couldn't be beat. I had an appointment with one of the technician between 1 and 3 PM. I recieved a call from him at 3:25 saying he was on his way and would be there in 25 min. He said he would call at 8:00 AM the next morning to let me know what time he would be able to make it out and didn't hear anything untill almost 8:40.
