Carolina Septic Pro review: Terrible company

We had Carolina Septic Pro from Concord NC inspect a septic pump that failed. They had installed a new Liberty pump 2 1/2 years earlier except now the pump was no longer working and they would not honor the warranty saying it only had a 1 year warranty. The Liberty pump has a 3 year manufacturer warranty. Their technician inspected the septic system. He said the pump had failed and that we needed to replace it. They gave us a price for emptying the tank and replacing the pump for $1300. They would not.offer and discount or honor any warranty on the pump maintaining the pump only had a one year warranty. When we asked to speak to the owner, we were told he was "out of the country".
The woman handling customer service definitely needs definitely needs additional training in customer relations. We had another company come out and troubleshoot the problem finding the pump at the bottom of the septic tank was unattached to the pipe system. It turns out a blown 2A fuse in the control panel was the problem.
