So, I don't talk to my brother on the phone that much but I do text him quite a bit. I texted him a few days ago and got no reply but that's not so unusual because sometimes we just don't happen to bother to respond. But I have now tried to ring him several times and his phone has gone straight to 'cutting off' rather than ringing with no answer. I'm just getting a little paranoid now and not quite sure the best way to go forward. Does anybody have any ideas?
