I received a call on my mobile from this number (07) 3144 4224 , a blank call, this is a some kind of VoIP diversion used, DO NOT CALL BACK THIS NUMBER it could be some smart ass hacker sitting in Russia trying to break into your personal identity.

Watch out.

Agree with all points above, something is not right with this number

I also called this number back - not from mobile in case it was a hoax call but from a landline - and it says the number is not in service - definitely suspect!
