AC Repair Durham

This is a dispatching service. They can honor their contractors work. They sent out Denham Contractors to repair my furnace. It worked about 20 minutes after 2 days to repair. I have been trying for 10 days to get in touch with someone and they are not returning my calls. I have paid them for services because I thought they had completed the job. I would not recommend this service or these dispatchers or contractors.
