Summary
Formerly Century Link, among other names, Lumen is a large telecom company that's grown through numerous acquisitions and of course has multiple resporgs and systems and probably numerous numbers lost in the cracks. They also work with a number of resellers, though not as much as they used to. This makes finding the right segment of the company and the actual company providing the service especially hard.
