"I scheduled routine maintenance on our heating system. I rarely have a day off during the week so I scheduled an appointment for one particular day that I did have off. I waited around all day to find out that they were too busy to keep my appointment. So even though I had an appointment, they couldn't keep their end of the bargain and actually come out after I waited around at home all day for them to come. Very disappointed in this customer service!"
