I keep getting calls from this number. When I pick up there is a delay then they hang up.
I have blocked the number (this is the 3rd number I have had to block due to this)

stalking and harassed over the internet by a person that has something to do with this phone number
mathew the person that is using the phone is not the owner of the service.
Confirmed by vodaphone i would like to hear from anyone else with this problem
thankyou

the caller called with music background and breathing on the first day. Second day the same. So i tried calling using different phone, no answer. then the caller calls back but is not answering
