If they state they're from Apple, it's a scam. It's that phony company, Click4Support; they harass people when they can't get any money or identity information.
its apple support.....i called apple with a problem and they called me back the next day with the solution from this number. Remember that anyone can put any number as their caller id. sounds like they are using the apple phone number to hid their identity.
This number just called me and I did not answer it. I do not carry any Apple products so they wouldn't need to be calling me. I do work for a cell carrier and they would call my business before my cell.
I received a 'no message' call from this number today. No message usually means 'no good'. I called the number and an automated voice greeted me saying this is, Avaya Messaging Services. I looked it up and apparently anyone can 'rent' this number. When you call it you'll be told to put in "the mail box number" (presumably belonging to the caller) or to "press zero for assistance". I pressed zero and all it does it route you back to the automated greeting. So it's not a spoof but someone wishing to remain anonymous who's renting a common number. So it makes sense that people may be getting calls from legitimate sources or technicians who are calling from their private number. However as I said, anyone can rent this number and I'm sure many of the calls coming from it are from scammers and bottom feeders as well as legitimate calls.
