Caller: Scammer

Had a missed call a few moments ago, no voicemail message left, nothing to identify who was calling, when I tried to call the number back, it said the call couldnt be connected. In otherwords, they were using a voip number which allows you to call out, but you cant receive calls in, as its not a real number - something that scammers use, and the call was in the afternoon, which is usually the same time these scammers call. Blocked it.
