Who called from 8586333474

Appears to be debt collection or something

Don't answer it! It's a collection agency

If they're a collection agency they must employ children. I picked up and all I got was someone dialing on the other end - then silence.

This number is calling me a couple of times a day. If I answer it, nobody this there or they appear to just press numbers in my ear. If I don't answer, they don't leave a message. This is just annoying.

When I called back, the voice mail stated that it is a subscription center for free trade-specific magazines.  I'm a software engineering guy and subscribe to many trade magazines---so it might be legitimate, but, then again, maybe not.
