Got a call at 6:35 in the morning from this number. I was sleeping. No message left. I called back right now, just out of curiosity and a message came on saying: The number you have dialed is not a working number. I called a couple of times just to make sure I dialed right. It's obviously a scam or sales call, if they do not accept incoming calls.
Same thing just now... 3 calls in a row... I called it back (just like others said they did) and not to my surprise, it's not a working number! Blocked!!
