Who called from 7204039878

This woman called and asked for me while I was covering the Front desk phones. I asked what this was in regards to and she said she was from occupational health and safety and then she hung up. You could hear other callers in the back ground - Call center

Answered a call from this number and there was no sound from the other end. They hung up after 11 seconds

I am receiving calls from 720-403-9878, no one answers on the other end.  This is a business that I work at.

"Reaching out to you in regards to your subscription renewal". Um, no.
