Who called from 5853973834

I called them back from my office line. The company is CVCS

Its called a few times in the past week. No one talks, but you hear the conversations in the background. Scam call

Spam call

Caller knew my name and said this was a personal business matter.  Said the name of some business but said it fast, I asked to repeat and still did not understand.  I simply hung up.  I think they are "spoofing" the number that is shown on call ID.  This call can be from anywhere.

This is a real debt collector. They are a company calling to collect money for a bill you have avoided to pay. This is a real company, they know the last 2 of your social which makes people uncomfortable but this is not a scam.
