This is a spoofed number. The company calls themselves "Glass Mountain" and the caller said she was in Illinois. They call my home and cell phone every single day and refuse to verify a debt. The caller told me her name (that was all) and asked who I was, if I was available, and told me to verify info such as my SSN. When I told her no way, she said she had all the info in front of her, but she couldn't tell me anything until I verified my info with her. Ridiculous, even for a bill collector.
Its a "debt collector" that never tells you whonthey are. Maybe if they weren't so shady and verified the debt that would amazing. I just block the number.
