This number called me at 3.20 am. I did not answer it, but the call went to message bank. I checked 101 this morning. No message as such, but I heard muffled male and female voices. I think one said, "Do you know how to do it?" Call came up as being from a known contact, but it was not her number. I suspect this caller has hacked her facebook /messenger account and made call via that method. Definitely a most unwelcome call.
