I am recieving calls from this number, when I answer no one replies. I am getting a bit worried about this caller.

Too dumb to show their name when calling people , do not deserve you to answer their call ; i do not waste my time answering any call with no name ...

I answered it, it took a few hellos for someone to respond, it was a woman selling windows

I got a call from them 6134822636  they did not answer and hung up.

Call came in at around 19:30 on June 27.
