Called company cell phone, no caller on the line, then disconnected.

They have called my office twice this morning. Once they claimed they were with RCS Construction. When you call the number back it says disconnected. Scam

Big time scam.

It's part of a scam...don't fall for it.

Just had a call from this number.  They left a voice message indicating they were calling from RLX Promotion, and that I needed to call them back at 877-551-4428 to have a package released to me.  Considering they did not mention my name, the company I work for, or any other sort of information that would narrowing it down to something other than a person calling people randomly from a list of numbers, it definitely sounds like a scam call.
