I've had a great experience with Vortex. Their customer service rep was able to answer every question I had and scheduled a technician to come out swiftly.
Christian came onsite today and blew me away by how knowledgeable he was about fixing the issue I had with an emergency exit door that was no longer opening. He was able to quickly troubleshoot the issue, provided more clarity on how this occurred, and ways to avoid this from reoccurring going forward. His customer service and professionalism stood out to me. I wish more service technicians were like this. He just raised the bar for every technician out there!!
